I love your face expression here and its a great pose. Congratz :3
(sorry for the bad critic, but i hope it can help to improve? although im not related to photography, so here it goes) I do think that the overall picture could use alot more work tho.. for start one cant see what kind of scenery is that and the little we can see from it, it doesn't seem to related to the costume, maybe I'm wrong. I cant even understand what's the black areas on the pic, if it is from the scene or put after to cover for something, it just look weird, because everything on your costume and the wall behind look so bright, even that light appear to be coming from this side, atleast in my head it is impossible for this to be supposedly taken from a dark room to outside.
I mean, what i want to say is, if this exact pic(pose, etc) was taken like this one: arashiheartgramm.deviantart.co… (in terms of lightning, etc) it would make much more sense and it would be wonderful.
(i hope i didn't gave a wrong idea of what i wanted to say)
