I love Boys and Girls from LM.C but my favorite song from them is Sentimental Piggy Romance. And my favorite sng of all times would be Jibun kakumei by Miyavi. Oh and I just listened ti Ouka by Kaya and I like it ^_^
Well, I don't think cosplaying doesn't need to be perfect but when I search people who cosplayed perfectly it's a great accomplishment. Cosplaying is only something I do occasionally, I most likely like seeing some friends that are girls pull off the naruto characters and even Misa from death note.
