Nice one, man... That's so realistic and dither is really organic...

very nice now! new colors really make it look way better and realistic! nice job man!

Wow, HUGE difference. Nice job implementing changes. I like how you chose to show the image progression too.

Thanks for the input shibumi and eldiabolito

I fixed the fused jaw issue

and changed the outlines then added aa.

I also decided to redo the colors

 and i fixed the weird lookin cheek bone

good detail!!!

Eldiabolio has a good point, that jaw bone is welded to the rest of the skull and it shouldn't be. I would soften up the cracks in the skull too. You're using the same color for the cracks all across the skull even though the light on the skull is changing. Lighten the crack as it transitions across the lighter areas of the skull and maybe darken the cracks a bit on the back of the skull. Some AA might be a good idea too.

that mouth for sure won't open ^^

Oh cool, this is great
