It looks a little hurried to me. the use of color is extremely nice, but the strokes are haphazard and somewhat sloppy. you don't seem to change up the brush size hardly at all.
if you were going for a quick impressionist thing, i'd say you were nearly there. but for impressionism you'd need to change up the colors even more, and make your strokes a little shorter and better-planned. also idk if an anime-style face would be a good representation of the style.
other than all that, it's cute

the critiques i give to people always make me sound like im being snide or something but i'm just being honest (you've been getting enough praise anyway, a little crit doesn't hurt!)
