This is a semi sketch, their could be heaps more colours and fine tuning but you get the jist of it. no reference.
updated this, thanks stitchy
Thanks Stitchy, I will fix it up. Yes she is pretty :)
I think this piece is a little too rough to be considered pixel art yet. Right now, this is closer to an oekaki. Sketches are generally things that aren't accepted into the gallery as far as I can tell. If you refined this, then you'd get a yes vote from me. ^^
Besides those technicalities, this is a really nice drawing! ♥ She's very pretty, but still has a "real" feel to her that I can appreciate as a fellow female.
