Well... you can start by straightening out the teeth.. a lot that one saber looks it goes directly into the tongue like no one business. Nothing reall wrong with the full head on the left thought the cheeks look a bit too puffy. The paw needs to look more realistic paw/hand whichever your going with. The claws need more curvature to look like actual claws. Also they need to be more triangular and smoothed going towards the base of the paw/hand. Other than that it looks good.

Hope this helps.

I am terrible at straight lines and good curves, but I'll improve. Thanks for the input!

No problem! Happy to help.
