T_M's Work

[E-Man]

It's a nice start; however, correct me if I'm wrong, but shouldn't it have more shades? I'm assuming this because your style seems to be trying to emulate the style of the remake. Besides, if you look at the sprites of the original game for the NES, all of them had three colors at most, while your sprites have more colors than that. Also, would you mind if you make your sprites bigger? If you compare them to the size of other sprites from the game, they are very tiny. Despite this, I think this sheet could go places.

If you need help on achieving a good SMB3 style, why don't you ask Neweegee? Not only is he good with the style, but he's also a swell guy!
