Oh yeah, it's Sonya. And she's looking pretty darn hot. I thnk mine looks better than the game O.o'' I know it looks a bit odd because of how her legs and feet look enormous compared to the rest of her body but I'm trying to mimic the style of Hyung Tae-Kim. You can look up his website on goolgle. He's my favorite artist. Enjoy.
You summed up the only complaint I would possibly have in your description there (about the proportions). Other than that this is very, very good. It's very detailed and very clean.
