I got a kick out of how the coloring is... umm... rather realistic in places... Anyhow, you've got a lot more talent than I've got when it comes to carving. Nice piece, and beautiful wood.
I sanded it with a 4 1/2 " angle grinder with a 120 flap disc. I could have easily sanded and polished for another couple hours. I would call this a rough finish actually. I used gloss spar urethane 2 coats as a finish. Here a couple more pics of that awesome grain!
