I do like the concept. Just a few things to remember as you finish this up. Make sure that the lighting is consistent throughout. The global light source is the sun here and since that is off in the distance behind the focal points of this piece make sure you keep that in mind when placing shadows. Also, the eye is somewhat reflective so you may want to remember that if you want this to be a little bit more realistic looking. Good work thus far though, especially for a first attempt.
