You see I don't mind pixel art, and even enjoy it quite a lot. But even I get tired of pixeling. Making a full spritesheet in a day is simply impossible for me. I try to make one animation per day and that seems to be my limit. Today's animation was Jieo's forward movement.
As you can see in the picture, my technique is very advanced and yet super simple. I sprite till I'm bored (usually one pose is enough) and then I play a round (or 3) of super smash flash 2...
It keeps me entertained enough to keep going.
