So with my fursona Rhelx being a male Saurian, I thought it would be a good idea to design what a female saurian might look like. The main physical differences, besides the obvious like breasts and wider hips, are shorter horns, fewer and smoother scales on the back, arms and face then males, and a longer but narrower tail.

And now some notes on why a female lizard would have breasts.
Well, mostly because boobs are awesome, but if you want to get all technical about it fine.
Not being true lizards, but rather anthropomorphized ones, I have decided that Saurians are not truly reptiles in the strictest sense of the word, but rather a species that would exist somewhere in-between the classes of reptile and mammal. Saurians are at least slightly warm-blooded, allowing them to exist in slightly cooler climates that most reptiles would be able to. Saurians, though hatched from eggs, take only several days before they hatch, and in keeping with their half-mammal characteristics are omnivorous and do breast feed when young.
