looks badass XD I'm a huge fan of lizardfolk fanart myself. I personally think the tail is fine albeit maybe a little longer with a thicker tip like that of a bearded dragon or water dragon. I love the head and jowel proportion tho and dig the way the abdomen sweeps right into the tail section.

Wouldn't mind a sketch for Rook if your up for it. I was thinking more lean than athletic. And about 5' 11". He would prolly be boring to draw since he's so normal looking lol
