I mean, she's only half reptile, the other half is humanoid, isn't it? It's like with centaurs, would the top half of a female centaur have breasts, or would their lower half have nipples for their young? How would they drink from the human nipples if they're so high up in the air? Do they lose their horse nipples?
Regardless, it's fantasy, and this is apparently someone's addition to the fantasy.
Quite so, and that's where the artist went.
She's a god, not a reptile, and thus can take whatever form she wishes, anatomy and reality be damned.
