I really like this! Cute but also menacing. The use of dithering texture implies scales and I love the smoke and eyes.
I'm a bit confused by the light source. The left claw looks like it's lit from above left, the right claw from above right and the nose from straight ahead. This could be because the right hand section is an almost exact mirror flip of the left.
This is fine if you don't care about the light source. That's up to you.
I'm *certainly* no expert, but a little bit of asymmetry can sometimes serve to make things look a bit more realistic. Picking one light source (above left for example) would mean shifting the shadow under the chin and moving the highlights a little on the right claw. Maybe a touch of work around the nose, ears etc. Or choose directly above and only the claws really need to change.
But that's just an idea. In all honesty it looks awesome.
