Giving him more human/bearded dragon like skin tone and less of a green color while also maintaining the reptilian scales and appearance.
I still prefer Reptile to go full on Lizard but, I wouldn't mind this. It's a heck of a lot more interesting than the ninja template they keep shackling him to.
Love the feral looking, shredded, torn top. You can see the oldschool base, and the new shoulder pads, pauldron ninja outfit, in a nice transition piece.
