I like it. Seems like a very functional tool.
Two things to possibly change. Increase the cut out behind the edge near the heel so you can choke up and do more knife type work with it, making it more versatile. Also, round, harden, and polish the poll so that it can handle some batoning. With it rounded and polished it could be used to help remove hides and make it more hunter friendly. The rounded, polished poll would also be more comfortable when placing your thumb or palm against it for finer tasks.
