I am satisfied with the results of the carving and I cleaned up some of the bumps with files. I use files for initial cleanup because I can always go back to carving if I see something I want to change. If I use sandpaper I would not use carving chisels any more since the sandpaper would leave behind grit in the wood grain and quickly dull the chisels. I will sand the whole leg before finishing once all of the carving is complete.
On to the next foot, maybe I'll gain some speed.
