The only thing that is quite disturbing is the fact that you wish to portray Ezio climbing, but I see no strength in his hand, as if he weighs nothing or just standing there. I think it would have made the picture more powerfull if you 1) put the focal point MORE on the hand (it seems to be out of focus a little) and 2) show some more strenght in the hand!
Thank you very much for your comment!!! I really appreciate your suggestions! Actually the cosplayer didn't like the pose very much, so he wasn't very into it while I was shooting, that's probably why he didn't put much power into it! But, thank you thank you thank you!
