I highly recomend to download it in 1920x1258!!
Yesterday i've posted another drawing of this girl. That was a sketch that i've done for an event (she's some kind of mascot), but it was a discarded sketch. This drawing was chosen instead the other one. And this pic will be plotted on a vehicle so i made it pretty huge. It took me like 5 days to finish.
Basically, the girl is done entirely on SAI. In counterpart, the background is entirely done in Photoshop CS5. The original pic is 8000 pixels wide.
Hope you like it! (because i love her)
