If you think that's hard you haven't seen many custom wads. Like the next-gen sonic for example. Anyways, I think you're doing pretty good for your first wad. But that's too big and I don't think there is a character to edit from besides the vgm wad. I think it might be vmg, I don't remember. (I do everything with paint and I've made some popular wads like amyrose and silver.)
