Ok this is my sprite sheet. Characters here are created with the RockMan7 sprite style. This entire sheet shows my efforts to make Tsukasa and Subaru from .Hack//Sign.
Tsukasa was closely based on Rockman's body, however, Subaru's body was sprited from scratch Subaru's hair how ever was a challenge for me. To overcome this problem I took a look at Punk - a Roll based sprite from sub comic Dysfunction over at Bobandgeorge.com In the end I doubt I got her hair "right," but I got it as close as a Rockman 7 sprite could get it. The only problem I have to resolve which I've been working on is Tsukasa's height. Because there is nearly no details on his lower half, it is difficult to crate a ballenced looking sprite.
There are hundreds of better places to show off sprite sheets. and your use of megaman sprites as bases make these entirely banal go find some good fighting game sprites. also, it's unnessecary to show more than just two standing frames if all you're doing is adding and removing props.
