Thanks guys.
Gary - glad you like it. It was alot of fun. As far as advice on getting a good likeness, I'd say here are couple that have helped me:
1) Get reference pictures of your subject from as many angles as possible. You can never have enough. Try to at least get full front view, profile and 3/4 view minimum.
2) Use calipers to check measurements. I used a drawing compass. This helped me check proportions specific to the subject.
3) Look at the features that are really prominant on the face and be sure that they are used in the sculpt. It might be obvious, but in my case, the subject has a very distinctive chin and mouth that had to be right to get the likeness.
4) Practice. I've done some portrait pieces in the past that were slightly to moderately successful. The results here are because I had made my mistakes (before discovering a new set of them!) on previous work. I had also picked a subject with plenty of reference photos available
Hard to say beyond that. I study lots of reference books on drawing, sculpture and portrature as well.
Keith - if I do another BoB subject, it would be either Capt. Sobel or Sgt. Lipton I think. Maybe Lew Nixon.
