They all look really good and look how far you have come already, now you need to step it up a bit, here goes...
Teeth and claws: They need a bit more definition where they meet skin or goto apoint, look at the teeth on your trog they look very one dimensional atm, where as the claws look better but would benefit from a bit more work so....
Teeth: wash with Agrax earthshade where they meet the gum, add white scar on the tips.
Claws: try highlighting the ridge and tip with white, maybe a wash where they meet skin.
But they are fine as they are and I'm only trying to help you see the next level this is by no means me saying it's bad far from it, excellent work so far.
