Wow! Nicely done. The detail around the mouth, feathers, and hair is great. A couple of things to add as you continue in this craft...watch Joe Meling's video on tooling leather feathers. It will assist in getting the lines going in the same direction. Also, Bruce Cheney has a couple of videos on beveling. This will help remove the light and dark spots around your circle, making it more consistent.
If this is for your table top, thank you for your service. Thanks for sharing a creative, and daunting carving with us.
