It have big and small legs with big foot like some elephants
or animals like Rhino.
So i think it's some sort of new Troll race or mutant troll : Good

Perhaps it could have been done more menacing with the face with a thinner nose ? ( It looks kinda gentle and non agressive )

Trolls : i never seen one, they mainly come from imagination, why should we all make always the same trolls style and proportions with very samll variations ?
Why not making a troll having some crab calw in place of one hand and arm ?
