Hey Charlotte First off welcome to TDA! I think you're off to a great start with your gallery already, well beyond Member Artist level, so you can def expect a promotion soon I'd say right now you're about Junior-Senior level, and I can definitely see a certain style developing, which is always great when it's this early on. I like the minimalist, texture-heavy thing you have going on, I think it works really well for you.
You mentioned image quality as being one of your weaknesses, and it's really not that massive of an issue. There's some very tiny LQ-ness going on, but it's nothing too bad. To me the Lily&James banner looks a bit oversharpened and pixellated, and on your Barbara Palvin sig the bigger Barbara looks a bit undersharpened as well, but that's pretty much it. I love how crisp the All We Do chapter image is! I guess for image quality just watch out for those small things here and there, and your eye will get more used to picking out over/undersharpening.
Your use of text is awesome as well. I like that you've got a big variety of different fonts and colors and styles going on, it's nice to see that you're not afraid of trying different things. I especially love the text on the animated Bucky banner, I think it works so well with the graphic. Honestly no complaints here, just want to see where else you can go with experimenting! Definitely keep doing what you're doing with text. Keep on trying new things!
In general I think your comp is quite good as well. The only thing that isn't that great comp-wise in your gallery is the James & Lily banner. To me it looks a bit unfinished, and I think even though the sides were meant to be empty, it's just a bit too much empty space. Maybe if there was another texture, or another girl in the foreground. Text is great though, but the image quality is also a bit of an issue. I'd say this banner is the weakest thing in your gallery, and I would maybe remove it BUT you don't have any other banners in your gallery so maybe that might not be a good idea... I know when it comes to promos, the admins always like to see the different canvas sizes and graphic types that you can work with, so I'm not sure if removing it would work to your advantage. But something to think about anyway. I'd definitely suggest making more things! Right now your icons, CIs, sigs, and banner is great, but I'd love to see maybe a blend or a book cover or more banners in there.
ANYWAY back to comp, everything else is nicely comp-ed and nothing's coming across as too repetitive now. Comp of Pocahontas sig especially is gorgeous love the textures you've used and the colors are beautiful!
Ah okay, so you've listened banners as your final weakness, and I think it's a bit hard for me to judge your banner-making ability based off of one banner alone. To me your CIs and sigs are gorgeous, so I'm sure you'd have no problem with banners. The 700 x 110 is definitely very awkward and I've certainly struggled sometimes with making it work, but honestly just keep making more. Even if you think they're turning out like crap in the beginning, I can guarantee you you'll start to enjoy these long rectangles. For me they're the most versatile graphic type and I think also the most interesting to work with in terms of composition. The longness sometimes makes you position or comp things in new, never-before-tried ways. So I don't think banners are a weakness of yours, I think you just need to keep on practicing them For me a great place to start was the requesting arena. I would avoid banners so much that the only way I could make them is if I picked up a request. Usually those are less creative pressure on me because it's someone providing you with the images/mood that they want, so I just kind of used that as a no pressure way of practicing.
All in all, like I said, great start with your graphic-making. You're definitely on the right track already and I just know that you'll be shooting up the ranks in no time as you start perfecting your style. Definitely make more stuff! If you have any questions feel free to PM me, and I hope I've helped!
