Hi Sharen As I said: "This is important to me in my commerical work. Some clients do not like any other artist name credited unless both artists are on the contract. They want to make sure the is a clear copyright on what they are buying." The model would be part of a larger image such as Book Cover, etc, I don't know if you consider that "taking credit for the creation of the model" Please understand I have not purchaseed any of your models, I was just concerned about the "terms of use". I'll have to check anything I buy now,just in case.
