Iron, you pull off that cosplay better than anyone I've ever seen.
If I can say, though, and please feel free to just ignore me, your legs are always pointed inward, and I think that takes away from the strength of your upper body poses. It looks like you've done that in all three of your photos. I think this last photo is my favorite out of the lot. The first one is cool looking but has that "Now POSE!" "Uhh, okay. *pose*" feeling. Especially since I can't see your face at all and that makes me cry ;_;
Anyways, all that fully-good-intentioned critiquing aside, I love your outfit. Are you wearing it to Kumoricon or was this just for Sakuracon?
