I like your finish, for your color and your application. One thing that catches my eye is the position of his right hand, though, and this lies on the kit. I think his hand should be cocked more with his thumb to the wrist, which would give the sword a slightly more horizontal angle, but also one that would look more natural. But as I said, I think that's the way the piece is sculpted, isn't it? The two straps dangling from his obi might also stand a little prouder as they lie across the folds of his kimono, too, rather than following those contours. I like how you've highlighted his expression, too.
Thanks for showing us your finished piece! Prost! Brad
