I personally like these a whole lot. they're cute and stylish and get the job done. To me, the shading on the hair seems a bit random. And those two pixels on the top of the head stick out too much from the outline. Also, in your jersey you're using straight greys. Try to avoid 100% desaturation. Greys are alot more interesting with a hint of hue in them. Thats it for now, i'm leaving for an appointment. I might come back here for more in-depth critique.
