I know what you mean..I see a lot of JP and other dinosaur figures used in outdoor dios..but I would say your the first to actually use these type of statues. The closest anyone else would come would be the 1/1 pieces you see in parks and such.
Yeah it would a lot easier if you had a double you could dirty-up, even remove from it's base and use the natural turf for shots...imagine finding a nice patch of dried up mud and just setting the Carno down on it..maybe add a smaller dinosaur toy out in front escaping..the one element they left off but hinted at in the orig piece.
If you do the Para set..think it would be an adult running away from the carnage or running in to attempt to save it's young ?
