I would agree that even if you feel burned out that you should continue on and finish it because if you don't I am afraid that sculpting may become to intimidating for you and you obviously have a talent for it, and are using your anatomy lessons to good use. And yes the body is often the easy part, but if the rest is normally your problem then maybe draw out several views of what you want for the hair and weapons to get a feel for them in two dimensions and the depth perception you wish to achieve. Perhaps that will help some.
