So far I've done X-23(Target X version) and Layla Miller(though it was kinda rushed so I'll re-do it someday)
I'm currently working on Squirrel Girl, X-23(New X-Men version[black]) and some form of Kitty Pryde. I'd like to do the Wolverine and the X-Men one but I'm not very skilled yet so I'm thinking maybe just Excalibur with a Lockheed and Widget at my side.
For the future though, I'd really like more Kitty/X-23 costumes and I'm DYING to do a Dead Girl costume. She's so rad.
