As if Bowser remembered Smash Bros

[triptych]

didn't really read any of the posts here so far, but the main problem i'm seeing with this

is that even though it looks like you're trying to give it depth
it still looks extremely flat

look at this:


this character has relatively the same sort of build that(at least the lower half of) pikachu has

see how much more depth it has than your sprite?
fix that
