The hair from the front/back looks kinda like a christmas tree, maybe vary it instead of making it symmetrical? At the very least change the spike length or add some smaller spikes. Might be a good idea to remove the shine from the top on the back view- it's not consistent with the other views. Got some banding on the top of the hair for the side views. I assume the legs have some kind of kneesocks on them- if not, make the color less red and more brown, maybe change it from a straight line on the front/back view. Lastly, the view on the feet is inconsistent- it appears to be from slightly above in the front shot, but it's side-on in all the others. Maybe have the feet visible to the sides in the back view.
Sorry for all the nitpicking. It's good stuff aside from that, you've been improving a lot.
