I was notified of this by the PPG artists club and saw that a critique was requested.
First off, very nice work. The shading is done very nicely and I love the effect on her eyes. The shading on the bow could be a bit better but it's still great. It looks almost... realistic. Lineless pictures look really realistic. (Probably because in real life you'd never see a person outlined in black.) I adore the way you drew her hair! That is probably one of my favorite parts of this picture.
Originality... I have never seen this pose before, but something tells me I have. I don't think so, though...
Another thing I like is the font you used for Blossom's name. If I'm not mistaken it IS the font for the PPG logo.
Overall, I really like what you've done. This will be in my favorties.
