I think you forgot to add her eyebrows. ^_^;
I actually like the image of Jellal (Gerard? Gellal? I never know for sure, lol) in the background, it adds to the nice screenshot-y dynamics of the wallpapers. The skin could use more detailed strokes in places like her nose, arm lines and lips but it turned out okay for your first try. And I agree that color red is very hard to work with, adding some hues of purple or even bluish gray on multiply and lower opacity might do the trick for shading it.
Nice job overall and keep it up!
