Once in a while, I do make my own sprites from scratch (such as my avatar currently.) :) Even Battle sprites (well, I only made one), but I don't think me alone will be enough to, errr, create a seperate sprite section. That and I also don't base myself in sprites.
But, hey, if it's going to be made from scratch, it's considered art so might as well just stick it in with your other fanart. No biggy.
