Big improvement! Nothing major to crit on except som tiny details. The pose, doesnt look like he could stand on all 4 limbs without the knees going underground or if hes suppose to stand on his back legs it looks like hes falling forward, the angle of the foot make it look like its standing up on 2 legs. And you could still push the asymetric treelike feel on som parts… It will do with just details of difference. But as it is now its very much up to taste so if you are satisfied, keep it! I know its just a sketch so far, so ill just sit back and wait for an update! 
Good stuff!

the mouth is a bit odd imo… but I like the overall look of the head… but those small teeth (and does he eat or just bite? looks like they’re made for eating) …and the cut off nose… it looks a bit odd and unnatural.
