Some of it looks screwed up but it's a work in progress.
sprites are blocky looking, but you said this was a WIP so yea, just make the sprites bigger so you can add better detail and make them less blocky looking and fix up some things like strongsads misformed head... Oh and whats up with the halo thing above homestars head?
Not too good. If you want to improve your Strong Mad make him more of a block.
In a way, this looks like something the Cheat would do when he's not drawing/animating. But yeah everything is too small and blocky or too small and rough/jagged. The background is also too small and two-toned.
Lookin' at Strongbad makes me think of the Chaos Emeralds.
Can you make it bigger? It's too small.
also, i know its wip, but the shading could be better >.>
