RRRRRRRRRAAAAAA!
What do you think?
First thing first, very interesting texture on Rex :-), choice of the lightning also creates atmoshpere, that the Asteroid is coming for Rex tail.
I think you have a good result, would try to make some edges smoother, so the body is not so blocky.
Very interesting image, I love it as an intricate origami work with an interesting light. It may be a bit blocky, but it is consistent with the trees, so it is within style
This said, I think that the tree to the right of the dino is a bit “floating” on the surface. The light and its own reflection can be seen below, and maybe it would be better to avoid it so that the tree looks the same as the others (though I would keep the rest quite the same at this point).
That’s a neat look; a T-rex with chicken-pox is certainly not something you see every day on your morning commute! XD
To improve it, I agree with Gaatser in that the body could use a bit of G-G love to soften those square corners, and you may also want to give a different material to the inside of the mouth. Nice job!
Add some eyes and teeth he looks harmless at the moment!
