Thanks guys. Yes, the prints are a quickly painted photoshop mask. The veggies are a mix of some 'modern' and ancient to get a nice image, but I'm not sure how scientifically accurate they are. I would have to do more research on specific biomes and all that. I might, in due time.
@KlausK ; the 3 guys are not interested in the mosasaur, as they don't eat (dead) meat. I was just thinking of making another render with them eating maybe large reeds or papyrus, or something green and extinct. An image is already in my head, so now I have to force TG to do what I want
