interesting - but more work is needed on your hole. The rock texture is leaking through. Maybe select part of it and rotate it to vertical rows, then layer that with a little warp for curvature for the inside of the hole?

Fun image

Shadow is not correct. See tree and wall shadow at left side of picture and create shadow in this direction with less blur.

i liked. good luck!

fixed... SOME more

Checking the hires - you might want to refine the edge under the chin? it looks like some grass?? also maybe at the ear also? Hole is looking better, maybe a touch more shading darker the further down you go?

Reminds me of the dying holes in the movie Madagascar 2 Escape to Africa. I have 3 kids and for a while it was the only dvd we had in the car. So everywhere we went they watched. Even to the store.

Very nice
