Ok you wanted it, so now face to my comment. I will be much harsher as the ones before me, and I absolutely don't agree with the most of them.
I say you direct, I don't say any point what you want to achive with this wall. Can look from any side, I see two different images, which don't matches except being from the same series.
One is colored, second not. The quality of the EVA is crappy, jaggy all the ways.
Also look on the proportions, how can the EVA being so small compared the her? And text should be never included direct on the characters. Give besides or even better, no text. Why starters wanna put always on walls? Is a wallpaper, not a info desk! Character names, title and etc. is meanigless there. If you wanna text do some good sounding sentence or quote.

My suggestion to it: work with one or the other image.
Even if you might gett accepted the current version (after getting better the EVA quality) doesn't await any good rating or comments.

Mmm...I guess I know what you had in mind with this, but there's too much contrast between Asuka and the Eva as a background - the transition between the scan of her and eva is too apparent. You might want to blend things a bit more like darkening the eva BG in the dark places where the Asuka scan is.

Also, the text is a nice one (in term of words) but you don't usually put it in the middle of the wall unless it's completely empty there. If you want to keep it, try a more subtle color and put it more below so the eva is more visible. I hope I helped you some. Good luck! :)
