you know a solution might be to, instead of drawing individual eyes, just sort of shade the socket area and let abstraction fill in the rest of the details in people's heads. It's a technique I use a lot and lends a lot of impression of detail where I can't actually fit it in.
As for what feels wrong, the head still moves a bit too jerkily there. Try letting it rest at one side a bit more before returning to the middle. It should also start moving a frame earlier than it does, it feels out of synch with the body as is!
