Alright, Billy! Always liked Katana back in the day. Her mask could be a little sharper and the sleeves a bit lighter, and the whole thing would probably look tighter if it were smaller, but why nitpick? Cool!
Nice work. This is good costuming, I like the sleeves and the furry bits (I guess) on her boots. Cool pose as well. Again, you need to feather the selections before copying. Also, I think the glint of the swords would work infinitely better without those blue lines. I mean, have you ever seen huge blue lines around a bright reflection in real life or in photos? Besides that, both the character and (especially) background are very pixellated. You may want to check out some of dperceful's tutorials for cleaning up skin in the comics2film art school. Those apply fine to cleaning up other things.
