>>1455509So a couple of things I'd point out:
Red: Lots of extra lines which look like artist mistakes/re-drawing of the shape of the hair. I would argue you could leave them out, it makes it messy.
Blue: I would put the hair over the eyebrow.
Green: Blush is different shades between the two.
Pink: Line end showing
Yellow: Not sure what's with the yellow bits, again, could be left out to make it neater.
And then in general get rid of the blunted ends all over. Hope this helps.
