Boy, what have I put myself into... That pose was a pain to set; this is the only picture out of two dozens that came out trying to get it right. But of course, one of her twintails somehow goes trough her chest. So I set myself to go and try manually fix it, buuuut... Yeah, as you can see on the screenshot, things are not just there yet. While I do know some very basic stuff about drawing, I need to learn more about highlights and shading; it is obvious that I had no idea what I was doing on that front XD.
So after two hours of tinkering, I just stoped there and called it a day. I will work on this on the side and hopefully fix it properly one day.
