Anime Central

As it is getting closer to Anime Central, I'm sort of freaking out, since it's my first convention out of state.On top of that, it's my first cosplay, and the first time I will go to a concert....I think I might die from excitement....
Princess and I plan on cosplaying Maya and Aiji from LM.C, and I'm worried if we mess up
             
update:we failed mainly since our hair dresser decided that the hair color and styles should be different
