I sincerely appreciate you posting a reply. I use PS CS5 (I have extended version). I looked over your portfolio; you do great work! However, I am skeptical because I am still quite awkward with PS's "extended" 3D, in fact, I have never used it and accomplished anything I like well enough to show anyone or include in my portfolio. I think I need a mock-up similar to a T-shirt mock-up: transparent background, provision to change fabric color(s), and capability to drop the artwork on various planes (front, top, and sides) via smart objects.
