I think you should work on the extraction more and clean the scan. Cut the grass in half I think theres to much. Change the font to a more cursive magical one. Then work on your sky with differn't shades of yellow, orange, and red you know sun set colors to give it more depth.

I think you shoudl try vectoring the main character. And like Tikal said, redo your background. You are new to walling so patience is what you need to vecotring and going walls.

About the wallpaper:
the bg colour is nice, and the clouds too.. but you should get ride of the stars and work more with the grass.. the grass is really not nice.. try and find some nice grass brush.. or you can try and draw it yourself.. you can find many tutorials in the web...
the scan need cleaning.. i think you should vector it like the other people have said..
the font you have used look not that nice.. try and find some nice one.. and i don't think you should write your name/sig with such big size...
hope that helps :)

The scan does have some extraction problems, I see alot of red stuff around him.
The scan is also grainy, you need to clean it.
The text needs some work, as others have said, try something more cursive.
Like Tikalhammy said, there's too much grass and you should erase some of it.
The sparkles aren't really needed there, and I think you should put mroe clouds to make the sky look more realistic.
Good luck!
