But the whole point of the game is you can be who you want to be, act how you want, look how you want so that your character becomes unique, with their own personality, own background story ect so that every person who plays it plays it differently. But as a game, they have to create a default character for people who can't be bothered/don't want to create their own character, and the thing is, the person who created the default char was probably a man.
I think it is lovely, and I love how you made the frills on the side of the head... looser, for lack of a better term. It instantly looks more feminine, while still being true to the original look of the Drell.
The Drell are not amphibians. They are reptiles, and live in arid areas. Their new "homeworld" is the world of the Hanhar, which is... wet, for lack of a better term, but to drive home that the Drell are biologically unfit for this climate their number one cause of death is Kepral's Syndrome, brought on by prolonged exposure to humid climates. If amphibians died because of moisture in the air, I do believe there would be a lot less of them around.
I do believe only mammals have breasts, and of them, only we as humans have breasts as we know them. That said, our lizards are not bipedal, with perfect memory, and a proclivity for interstellar assassination. By that I mean there is such a thing called creative license.
