Looks good for a first attempt, especially using steel tools. You're much better off doing percussion with something softer that will "grab" the platform, like copper or antler. I like antler myself. To make billets from your antlers, just cut the base end to a comfortable length, take off any tines and round off the crown in a dome shape to use as the striking surface-it's the best, densest part of the antler. For the copper wire, twisting with a vise and drill will harden it a bit, then just find a piece of wood about broom-handlediameter, drill a hole in the end, and put a piece of wire in it. Hammering the point onto the wire is better than grinding it.
