Well first of all, I love the shading. Cross hatching? Was that what you implemented? I also love their eyes, even if they don't follow the technical jargon on the race page:
"White and drop-like eyes enable them to see in the dark. "
I always thought it was a bit strange to have no pupil or iris or whatever. Granted, they are reptillian, and depending on what you look at...
(Gecko)
(Iguana)
(snake)
Shape varies, but obviously they still have those rather vital components, the contractile elements of the pupil that can pinpoint what you're looking at like a camera's lens, etc etc etc. I was never certain WHY they were given eyes without a pupil, after a bit of digging what specifically NOCTURNAL reptiles I could find (since it specifically mentions it's a component of seeing in the dark) still were not in possession of an eye minus a pupil. I even looked up the components of an angler fish's eye, just to see if perhaps what they were going for was more deep sea dwelling fish. But same result:
So I dunno!
The ONLY thing I might add to the image would be that headfin. It's a very distinctive part of what makes a klyros, well, a klyros. "They have an oval head decorated with a multicolored crest starting from the forehead and ends at the base of the skull that make them look like a fish. "
