Ok, well...here's what I whipped up.
Nakoruru, and Rimururu have been re-shaded, and slightly changed...not as capcom-ish as I wanted though.
And the Roll-lookalike is called Roll alpha, and there's a reason she looks like Roll.
Still, for MVC-ish Nakoruru, and Rimururu, I'd try to sprite aditional frames for attacks if neccesary, and custom stuff like spinning, a la MVC.
For Roll-alpha, I'm planning to make her more a of a brute than Roll...basically meaning, she acts like a tomboy, relies more on force than anything else, and using different specials.
...I might not be able to mugen-ize my ideas, but I want to at least try.
But, who should I work on first? And another question...how do I add a poll?
