I agree with Arne's crits, but I think there are still some anatomy issues.
I think the torso and shoulders are too thin (I think Arne made them thinner, too). Since this fellow has wings I'd imagine strong back muscles, and that pose would emphasize the lats as well.
He could use a neck.
That's at 12-13 pixel head so I understand no nose, but I don't understand the lighting on the bright cheek.
I think the center pleat of the skirt/kilt thing should be a bit longer since the left and right sides are held out by the legs at an angle (which would eat up height). not much, maybe just a pixel or two.
