Order the lionesses from prettiest to... not so prettiest. You do not literally have to be attracted to them to answer this, it is based on design
If you're forgettful ike me, I will provide a list:
Nala
Sarabi
Sarafina
Uru (DJCoulz depiction)
Kiara
Zira
Vitani
My personal order:
1.) Sarabi is just so pretty.
2.) DJCoulz's Uru
3.) Zira
4.) Sarafina
5.) Nala
6.) Kiara
7.) Vitani (her cub form is cute, but her adult form makes her look kind of like a maneless male lion :B)
