Did drawing sprites on the NES take a lot of creativity?

[Cobalt Blue]

my dibs are on that the ingame sprites just suffered from some small, glitched tiling. one should be aware that most of not all of the sprites on the NES are composed of tiles made up of 8x8 or 8x16 pixels who move along in a coordinated fashion.

in fact, if you divide the sprite in 8x16 blocks you'll notice that the displaced part fits perfectly.
