Usually we're limited by both the original sprite size and the 3 color maximum (2 colors if you include the black outline). I mean, if you're going to create a big walking dick instead of the original character, it's a lot easier and you can make it look better, like my recent "Unified Army of Testes Vs. The Nazi Unicorn Super Squad", but if you only have a single 8x8 block, the dicks gonna look bad no matter what. Plus crudely drawn cocks are pretty funny.
