I love the butterflies! the clouds are very nice. did you use a stock photo for those? pretty pretty~
here are the parts that you could improve
- next time when you use the grass brush, try making your forecolor and backcolor different greens. Heres a nice
tutorial on grass.

I think se-chan gave this to me. its very nice. your grass looks good, but its all one color and doesnt have any
depth.
-try using stock photos of trees, find a tutorial for trees in photoshop, or use trees from another anime image. Nice effort on them, but if you use a brush, they just dont look like they are part of the wallpaper. the trunks of the trees go up a little too high also ^.^
-the water is so pretty! but it looks like they go right into the grass (trust me on this one - I did it to one of my wallpapers, and alot of people complained about it.) so try making a little sand bank that slopes gradually down from the grass into the lake. it helps alot if you search for some images on yahoo or google and copy those.
oh and heres just a little suggestion - if youre going to add butterflies, I recommend adding some flowers also! Usually there are flowers around where there are butterflies! it would also add some more color to the wallpaper.
otherwise, very nice improvement~
