That's looking almost perfect. Well done, really.

But don't stop yet ;-)  It's always the last 5% of the work (or maybe the last
1%!) that really 'sells' a computer graphics rendering. And that's usually the
most difficult and hair-pulling part, because the final tweaking is so subtle at
this stage.

The *only* thing I would say is that the bright parts of the indents don't have
quite enough 'tonality' or fading-to-darkness as they recede into the pits. Your
lights code looks right, so I'm thinking that the gradient y pigment might be
scaled too deeply into the surface (in other words, fading to black somewhere
*below* the bottom of the pits.) OR, maybe try reducing the diffuse value in the
finish. Which will naturally make the SURFACE darker too, of course ;-/  Yet
more tweaking...

But the result will be worth it!
