I love how a single character has so much content inside of it, but I just really hate how it can be...

h e f t y!

Some can have like so many sprites and unessescery long sounds for the part of it, although It doesn't bother me for a few, but It can be really traumatizing for others. I'm not saying that they're bad, its just it need to some level of improvement for anyone who has a low amount of GB on their hard drive (im not one of them)

Heres some of my choices:
any character made by Brergrsart
Miku by YU-TOHURU

thats all I can think of :P
