I think your wall has a lot of potential going for it. I like how you tried to use the same colors as the circle-thing under the girl's feet for your main color scheme, but I think the light blue hue in the background is working against you and the darker colors. And even though the motion blurr of the rabbits is sort of weird, I can so see this in a video game - so I think it works. The design/shape that is behind the girl is acting as a visual path of some sort, so you might want to think about making it more transparent and possibly giving some "paths" to the bunnies. I hope that makes sense. I really do suggest making the light blue clouds a different color - more complimentary to the boarder colors - but keep the clouds with the motion. Once again, the wall is based on a video game, so I can see this as taken from that world. I think that what you're doing here is great, and the extraction of your characters is awesome! You've definitely got skill, so keep plugging along at it!

Pst: You don't have a tag on the wallpaper. It's always a good idea to put your name on your stuff - that way you can take pride in your work and other's will know it's yours!
