Excellent job, Litst. The stovepipe on the back of the machine really brings the components together and the chains LOOK fully modeled. Regarding the use of a backdrop, I was unaware of that technique when I was working on the helicopter - although I did use it to create depth of field in my 15 minute cheese can if you have the courage to look. It never occurred to me to use it in the way you did. Bravo. Jim Z. a.k.a. Julian Boolean
