I think this piece is super stylish!  Would be at home on a 70's sci-fi novel cover.

Outch, there is pillow shading everywhere :/

It is obvious that you put a lot of time and effort into this piece. The shading on the tail and the phins looks very organic. I like it.

I think it's the red and blue spots placed where they don't belong that makes it seem like a thermal camera photo. Otherwise very good.

I laughed out loud.
Also, great texture of scale and fins.
Body is not that great though. Probably because contrast between red and blue is too high and it looks more like it's pictured by thermal camera.

I'm speechless
