I think it is as finished as it gets right about now. As for a frame, If I ever get to see it again (this one anyway), I will think about it. I also am thinking of a stack cut with three different woods, and then mixing and matching the layers for a menagerie effect. I have copies of that pattern still, somewhere in my storage unit. Just have to dig them out.
oh, and in terms of scale... the tiny little cat is about 3/8 wide by 1/4" tall. the whole thing was about 5 in by 6"
