I mean this looks amazing! I think for me the thing that would help most at this point is to smoothen out the dino movements. Right now hes a cracked out dino. If its movements looked more fluid and maybe a little slower I think the scene would benefit drastically.
One more little thing but isnt really a huge issue, The car paint feels very metallic. Not sure if you have a clearcoat or anything on it but that could help. It just feels more like a sheet of metal verse a surface that has true car paint on it.
Again this is lookin pretty solid and I think if the Dino motion was slowed and smoothed out it would be amazing
