Hi Rodrigo! I'm Ronnie, here with your critique!
Ok, before I get started can I just say how much I'm fangirling over your graphics because all of the Stranger Things characters featured? I'm about 99% sure that means you watch the show, which is great because it's currently my favourite and none of my friends are caught up with season two which means I have no one talk with about it. So if you ever want to discuss theories + the newest season + least/favourite characters, just let me know.
(Also, we can also discuss our mutual love for Shakespeare. Gotta love the Bard.)
Ok, now actually onto the critique. To start off, my favourites! My favourite thing in your entire gallery is actually your current sig, +this. To me, it's absolute perfection, in part because of Joe Keery, but also because 1.) the yellow colouring is to DIE for, it looks so good, 2.) interesting comp, 3.) really great text! Every time I see you posting in the forums I always stop and look at your sig for a good thirty-sixty seconds or so just because I love it so much.
I'll first address the things you wanted me to pay attention to and then move onto some other stuff I noticed. First, text. So text seems to be a struggle for everyone, so you're definitely not alone in your battles to find just the right font, and the good thing is that you can easily improve with practice and experience. The sig I mentioned before I think is an example of really good text because it 1.) Fits in with the rest of the graphic, and 2.) Is interesting—and by interesting I mean it doesn't just look like you arbitrarily chose a font and slapped some text on there. It looks like you really thought about what font you wanted to use, how you wanted it to stand out (such as with the white stroke, which goes along well with the lightening bolt), and the positioning (I love how it seems to flow up Joe's body towards the top of the graphic.)
Going forward, try to keep continuity and interest factor in mind when you're working on text. For instance, I think there's a lot of experimentation that can be done on +this banner with text. Right now, the words "The Nightingale" are just in a cursive font that blends in almost TOO well with the base. Also, it's too big, as it spans almost a good half of the canvas. (And this is a point that you should take into consideration for all graphics you make—watch out for the sizing of your text!) If you want to practice trying out different font techniques, here's a couple of things you could consider giving a go before settling on a font/placement you like the best:
1.) Making both words smaller and stacking "the" on top of "nightingale" and moving both words closer to the model.
2.) Keep "the" in cursive and change "nightingale" to something a little more distinct (since it is the main word)—could either be another cursive font, or something bolder. Again, stack one on top of the other and move it closer to the model.
3.) Playing with strokes, drop shadows, and patterns on "nightingale." All of which can be found by clicking the button in +this picture.
4.) Playing with the warp text features on Photoshop. In the text panel near the top (see +this image for reference), you can play with some features that will allow you to bend and compress the text, which used in moderation can actually look pretty cool!
5.) Give it some texture! If you have a texture you particularly like, paste it into photoshop above your text layer and press Command + Option + G on your keyboard (I think it's something like Ctrl + Option + G on PC??) to link it to your text layer. If you want a more subtle effect, play around with the blending mode.
6.) Making the "N" in "Nightingale" the only piece of text in a really distinct font and putting everything else in a simple sans/serif font.
And of course these are just a few ways you can play around with text and make it seem more interesting and complex. When making graphics, I would suggest trying out a few different options for text before settling on one—I rarely stick with the first text option I chose; usually the finished graphic will use the a second or third option, or maybe a combination of two of them. Basically, you want to try out a couple of different scenarios before closing out of Photoshop, especially if you're getting the vibe that something isn't quite working.
When it comes to text position, don't be afraid to move things around! Text doesn't have to all be clumped together in order to maintain the focal point. For instance, on +this banner the name of the author could easily go on the left side of the model, whereas the main text can go on the other side. Same with +this header—"DA Digest" could go on the left side of all the Natalias, and perhaps the "December" bit could go on the right side of the little Natalia, near the bottom? Just a few ideas, but remember to move things around to make a more complex graphic.
Another thing you said you struggled with was making your bases too stock/texture heavy. First off, I don't think there's anything wrong with using a lot of stock or textures on a graphic, but it's all about image selection and blending to make sure that things look neat and clean. I think +this header is a great example of where you've used both stock and textures brilliantly—the windows in the background with the moon near the top and the yellow of to the sides look great together and very clean. On your banners, for instance, such on +this and +this, I think the textures you've chosen have made the stock in the background too murky. In the second banner, for example, the sparks/light/fireworks texture is completely obstructing the beautiful stock you've chosen for your base, but you can still get a really pretty lighting effect from this texture by setting the blending mode to overlay or soft light or one of those blending modes, rather than something like lighten or screen. Same thing with +this CI—try setting the texture you've placed over top to overlay or soft light and see if you like the lighting effect it creates more than the blotchy white/black over top.
Composition-wise, I think this is actually one of your strong points! The comp in the Joe sig is especially good, and I like that you're already experimenting with putting multiple people in one graphic (such as in the Natalia header). Going forward, trying moving that multiple-person-per-graphic theory over to your banners as well, and make sure you watch out for covering up people's faces with textures. On +this header for instance, the lightning should be erased from the small Natalia's face.
Besides that, just keep adding to your gallery! (I'm looking forward to seeing more stuff in here soon, especially blends and CIs!) I hope this review was helpful, and please don't hesitate to reach out if you have any questions about anything I said, or want to discuss ST.
