Aye cnc it hard as normall

Software used, gimp

add the software used please, you should know better.

i like this top-shell very much, because its not just plain simple grey, but imo the teeth and the mouth in general doesnt look good at all.
teeth need more depth (this black shader you added should be on the sides of the teeth too)
also dont use this texture brush (the one i like at the top shell) everywhere... it does not belong in the mouth.
sorry for my bad english.. hope it helped

Add some blood around the mouth and on the teeth to give it some color, I think it might look cool
also darken the mouth and make it a pinkish color or add some saliva maybe the small mouth thing that the xenomorphs have?

Yeah was planning on redoing mouth teeth and shell on back of the head. Like the one at sides and back under main shell. Also no blood probably just drool around mouth .

WIP WIP

I think the blood woulda looked better

And maybe add some scars/scratches somewhere

Got multiple colours of the drool, still deciding

The yellow blood is a good touch, but it looks like its floating and/or not a part of the picture. Too cartoonish i guess.

do some more shading on the saliva?
