Very pretty.

I really love you're grass, and the clouds and stars are beautiful^-^ The stream could use some work, however. You might wanna try adding a bit a more 'depth'...and I think the blue lines take away a little...I dunno^-^ that's just my personal opinion.

Another thing about shading...I think the woman in your picture could use a bit more of it. Though, I have to say, her dress is quite beautiful without it^-^

The 'star' in her hand is pretty as well^-^ overall, I think it's a pretty peice...and can't wait to see more of your work^-^ (sorry I didn't leave a more detailed comment XD)
