Suths are not typically overweight. Any liiten would have similar proportions to this guy if they were overweight. That crest on his head is his ear. It has a delicate vent inside that can shift. Below his ribs is his genital sac. There would be a slight bulge. If a male liiten is sufficiently aroused then his penis will emerge out of that slit. (It's inverted. I got the idea from my pet iguanas.) Liiten males also have extra rows of pores along their sides. (notice the pores along the sides of his neck - both males and females have those) Like all liitens, his legs are hairy. His feet don't have distinct toes - just boney bumps and thick pads underneath.
This is a preliminary sketch, but it gives a general idea of what a Suth looks like: reddish-brown scales (Note: liiten scale color can turn lighter or darker depending on exposure to sunlight) and very straight, brown hair.
