Oooohh this is nice..
Her hair kind of reminds me of those abstract and slightly techy designs.. I really like how you combined a bit of flow
with a bit of spike. Her face seems a bit too "well-defined" for a girl.. as in the edges should be a little
more soft, but that's a pretty minor thing and I like being picky with good art, so consider it a compliment ;)
Personally, I think that the tattoo on her face should be a dragon (because I'm incredibly partial to dragons and
they just look awesome)... if you hadn't said that it was a butterfly wing on her cheek, I really wouldn't
have known what it was ^^; The sakura blossom you vectored looks like a cross between a lotus and a sakura flower, but I
think it works pretty well here. All in all, a very beautiful pieace.. I especially love the pink background :D
