I'm not familiar with your character, as there is so much animae, and so little time. But this is a great piece. The pose is done very well and you know he means business!
Though you didn't ask for a critique may I suggest another color for your background next time. I think when you use orange and green next to each other, it makes your eye strain. Perhaps a light grey or deep blue, but since his kimono is blue, I understand why you didn't use the latter.
