It's hard for me to do a critique right now, but I DID doodle on how I would have tackled it. I always do a sketch before I pixel the lines and add flats.

You should try and determine where folds should go and also try not to use dithering (that checkerboard texture) like that. I know you're going for a knit sweater, but there are illusions that one can create with different shades to make the same effect. (although I don't even think I'd go for a knit texture xD)


You don't need to copy me, but maybe it can help you as a point of reference.
