Eccy's 2D Spritesheet Galleria: T.M.N.T: Kickin It Old School!!!

[Ecelon]

I'm thinking of getting into sprite ripping and I've ripped Leonardo from this retro game: I'm just after some input, like how to improve the Sheet itself, or if the icon is good enough. Keep in mind that I haven't finished the game yet, so I'm not sure if I've got everything on the sheet.

ICON:


SPRITESHEET:

Spoiler

As for what's next: I've got all the sprites for "Kraang" and "Foot Ninja", I just have to sheet them. I've also got the idle animations of Raphael & Donatello. Let me know  what you think, so I can repair this one if need be, and before I sheet the remainder of the game!
