Agree with @nostalgicroxas here, the silhouettes of these characters are possibly too similar. The heads look fine, so I wouldn't change those, but when I look at these characters I see two people who both have a similar kinda square, bottom-heavy, bandy-legged build with about the same proportions, are both slouching and wearing long sleeved shirts, slightly puffy sweatpants and.... pointed medieval shoes? I don't get the sense that there's an interesting contrast or dynamic between these two characters. I guess if the point is meant to be that they're like Bevis and Butthead; ie. they're two interchangeable fools who are effectively treated almost like a single entity, it would work, so it depends on if that's the case, or if we're supposed to see these two as unique, contrasting individuals, their designs need more contrast.
