Oh man! I absolutely ADORE the colors!
One thing that I can suggest tho, make your champ POP a bit, by making her brighter than BG or darker, right now she kinda blends in with BG.
(I haven't checked forums for a week+ due to lack of PC) But now Im here, and ready to post feedback, and continue my own work!
Wish you luck m8!
Keep it cool!
