This is Lil Shirojima from the Nintendo DS game Lux Pain. The game itself sucked but many of the characters were memorable, and this girl was one.
Oh! Well the drawing is beautiful, I had no idea you were the artistic type XD It looks hand drawn, did you edit it at all?
Its actually one entire pic, here's it on my deviantart http://luneth22.deviantart.com/art/Lil-Shirojima-Lux-Pain-Updated-276418701
Yeah, I drew a couple in my sketchbook, hopefully I'll have time to ink them in Photoshop - next in line is Yuki, a girl.
I think Yamase looks seriously cool ^^ So tell me when you have more up, kay? 'Course only if you don't mind me seeing...
