Here's a really good job with the background, very atmospheric. But to be honest, I like the pose of Acrocanthosaurus from old work, it is dynamic. Here, the predator just stands still, as if not reacting. Therefore, in terms of dynamics, I prefer the old version. At the same time referring to a different situation, so I can understand the Acrocanthosaurus.Also, I prefer fully scaly allosauroids based on the available evidence. But in general, I would say that it is a good job, and I understand your desire to portray your version of this predator's integument.
