Very nice indeed! I like the atmospherics, the mist is well-used. The way the Torosaur's colorful "shield" is highlighted in the patchy sunlight is cool. I could see others arguing about the majority of the animal being in shadow, but I like the composition this way, with some mystery, seems quite natural.
Upping the quality of the water would probably require increased main Detail, unfortunately, though reducing smaller-scale roughness can help.
