out of all the things on this picture I think I like the background the most then again, Twilight's expression is awesome too, but her tail looks a little bit flat, compared to the nice depth on the rest of her body
Looks great mate. Cannot find anything to nitpick about
On another note, do you think you'll be making a piece with a strong lineart (along the lines of your last RD piece, maybe a bit stronger) anytime soon? Being a tiny bit selfish here, but since to me it complements your style quite well, I just thought I'll ask.
Actually, believe it or not, I much prefer doing the defined lines with my new tablet. They are much easier, and help to define borders much better. That being said, this has been on my computer for a few weeks, and I just wanted to hammer it out.
