My concern would be with the humerus, its size, range of motion and ability to articulate in the way demonstrated. The femur offers another problem, but if the ribs are slender enough it works. It is more my concern that with three feet off the ground and a back leg driving its motion, the dinosaur would flip over end to end rather than run.It is a gorgeous model, perhaps when other poses become availible I can grab one. I like the texture and detail especially, and how the head is done.
