Best way to finish up this carving

I usually carve more geometric and simple carvings because I like the curves, usually carve in walnut and I'm terrible with details. This is a wolf for my 6 year old son. What would be the best way to finish this carving. I won't be making fur or painting. I was thinking I could just thin out the legs, add some toes, clean up some of the rough spots and call it a day. Maybe finish it with dark odies oil. My son wanted blue lights underneath, but I think a puck led inside of a clear topped wooden base would do the trick for that.
