It's a demanding model yes, But so is poser 5, Anyone who can make poser 5 fly will be able to work pretty well with this model. Virus and I both created the Alien, I made the head he did the rest of the body and sent it to poser, So he did do most of the work on it. However I am rebuiulding all the parts of the body to have a version I modele3d all on my own.
