ok, for some real critiques...

Its really good for early digital paint work.

But i think you need to work more on your coloring

You need more than Red in there.

Some blue in the shadows.

Some yellow, and orange in the highlights.

Theres a lot you can do to make it more interesting.

But right now its just too much variation of the same Red/Pink color.

And also, I presonally dont like how the teeth are done.
But thats minor.

Overall, really good.
