Pretty cool mod! The prerendered sprites, while they look great, they don't blend in with SRB2's artstyle as well as, say, E-102 Gamma does. I think it's because there's just so much shading. Not a dealbreaker, persay, but something to keep in mind. I'm curious why, despite the fact that the sprites are prerendered, you didn't utilize the full rotation slots? That's kinda the usual with these types of mods.
His moveset is great, although I wish his stomp could either be on a separate button(Fire, perhaps?), or give us the ability to swap the stomp and tail swipe via a console variable. I often find myself accidentally stomping instead of tail swiping. Another small thing, but he doesn't have any super form benefits. A simple infinite flight would suffice!
Other than that, perfect quality mod, I'd say! No real negatives to point out. 9/ 10.
