Hello! Here for your requested critique.

You have a number of very good graphics here, such as the icons, the last two banners, and the blend - all of which are senior-level - but some of the other graphics are holding you down with technical issues.
SignaturesThis and
this sig are extremely reddish, and the colouring is taking away from the rest of the graphic. There is also weirdness with blending going on in both, particularly with the stock images.
This and
this sig are also reddish, though not to the same extreme. The Mad Hatter sig might have worked better without those flowers on the left side, as they're making things too busy. And in the second sig, the image is oversharpened.
BannersThe first banner is fine on the right side, but that picture of Anne doesn't fit at all - either in contrast or in blending - and the text is clumsily done, especially with the quote. The text on the rest of your graphics is good, so I don't know what happened there. The second banner is well-done, and while it's a bit foggy-looking, it pulls off that style. With the third banner, there's oversharpening again, and the characters are too pinky. The last two banners are much better, and while I think they're still too reddish, everything else makes up for it.
BlendsThe first blend is an iffy one, as the left side is well-blended, but the right side is more meh. That extra line of text hanging there needs to go, and you should add more to that right side as a whole, maybe work with the main text so that it looks more naturally part of the image instead of just put there. The second blend is a lot better in terms of composition, colouring, and everything.
Hopefully this helps you!
