Lovely! Reminds me of those prehistoric times, a dinosaur crossed with a tortoise!
im glad you like it 
beautiful creature
Dude that model looks fantastic, u done a great job there.
But I got some critic though:
- the ground could have a better material (more detailed with bump and stuff)
- the overrall scene looks a little bit too dull, there could be more light sources to pepp up the look of the creature
- don’t hate colours mate (compositing effects can do a great job there, Im serious)
just to name a few
Have a good day dude!
