Pretty good, but i'd work on your lighting a bit. I know, working in a con area that it's difficult to get good lighting, especially when the lights hang so high, but there are editing options for that. Poses look good, however there are quite a few pictures where your cosplayers are cut off. That's a personal choice of shooting style, but I personally don't like shooting that way. Good overall, though! Keep at it!
