First things first, it's better than anything I've done and I like it. But, you did ask ...
I think if the beveling around the figures (and really all the carving), were sharper, it would all pop more. Some of the guys and girls around here doing leaves and acorn themed stuff really get their stuff to pop. I think they almost undercut the carving.
I admire the deft hand at symmetry in your stamping. Very nicely planned and executed.
Does that buckle not require holes in the belt?
