What real life lizard species are the Iksar based on?
 

I think it's either Komodo Dragon or Asian Water Monitor or Nile Monitor?

A triplet of “Widescreen monitor” options. Honestly not really much variation in the suggestions there pal.

The make up and frill of the females remind me of iguana, or maybe even some kind of ceratops.

The males are more like therapods/raptors.
