Blue I don’t know if this makes sense but the arm segments are uneven Try doing backgrounds, they don’t have to be complicated I have no anatomy tips Creative ocs :>

hmmm imma go with blue. i dont quite know your age or how long you've been drawing on digital, but your art is pretty damn good, and i recommend you keep working hard and you'll reach the level you wish to be at as Bork25 said, i recommend working on your hands. i know how much of a pain they are to master (i myself havent quite mastered them yet) but you'll get there, just keep practicing! <333
