Nice work! My critique would be that i'd rather the left side not be so "square". Any way to round it out somehow to match the right side more would be awesome. It's just not very balanced imho. Maybe have the cut routed out so that it follows the shape of the button but at half depth or something... ramping down to the lens. Still, good job getting it going and getting the original buttons in there! Oh, and ditto the alpine knob... i'd love one.
