This is good. What I'd consider practicing next is to smooth your lines out more, and adding a face to it. Of course, learn how to do faces first if you haven't yet.
Proportions are OK. The hands & feet need some work. The arm from the shoulder to the elbow & from the elbow to the wrist is not a straight shot. The joint at the elbow is wider. Check it out. I see you are branching out from your normal work. Good. Overall the figure is very nice. Keep drawing & practicing.
