Oriental eyes! Great job. It would be nice if you build the ring. About the name, it's supose to fight sumo or it's just the name? Then some reinforced "belly" would be a great addition. The lower legs are a bit blocky, if you use a similar design used in the arms it'll improve a lot. Anyway, it's great and anything less than we can expect from you.
Very nice, I agree the eyes are a very good detail. The legs are fine except for the feet which appear too small to support the frame, so perhaps enlarge those but otherwise I wouldn't mess with what you've got there.
