That's such a good cosplay.
I've tried cosplay when I was 14/15 but it didn't turn out well. I have tried Matsumoto from Bleach (my boobs were too small and the cosplay was shotty), Nyuu from Elfen Lied (it was okay, but the horn/ear things sucked). Next week at the sci-fi convention, I am debuting what I've worked on this semester, a lolita gijinka of shiny Umbreon. I'm pretty proud of it. Can't wait to show it off.
I'd love to try to cosplay something from Dangan Ronpa sometime.
