Now this is finally a fresh spin on the subject, I'd say. One can legitimately say there's enough Midna-stuff out there, but I find this one honestely original. The obvious thing would be her face. I can see how much effort you poured into it. Comes somewhat close to "photo-realism". Tender also. And a great choice of colour, the lighting comes out great for all of the painting. The background perhaps is the least interesting part but it emphasizes the charakter even more this way.
So what is left to say? Midna turned out just "beautiful". I really really like it. The more I look at it the more it stands out from the fan art crowd. You did awesomely well on this. Oh, and I just noticed that her markings do not glow. That's also kind of unique around here, I like that. It's details like this and the hair on her left shoulder that makes this painting look so realistic, nothing's stylized or anything. Instead, she seems to stand right in front of me.
