>>1547125Just go to youtube and search for 'pixel art walk tutorial', you can also just download walk cycles sprites and copy the movement, and from there create all the other elements separately then you can compose them on aftereffects if your final goal is a youtube video
For pixel art most people do it on photoshop just >copy paste as you modify them a little (add a shortcut to toggle layers on/off and a miniview preview window) >export as png sequence to aftereffects >compose your scene using precomps >render for as youtube video
