Aravi looks awesome, though, considering the randomized factor.
I usually find a picture of somebody, usually a celebrity. With Lady Saga i used a pic of Taylor Swift, for instance. Renee Gade, I used a pic of Xena. No, they don't look like Taylor Swift and Xena, but my point is I at least tried to
aim for these looks.
Since you're trying to make a cat-person, you might be able to literally just use a pic of a housecat or a lion if you wanna try this.
If you don't wanna try this, you can always do what Mara above me suggests; play with sliders. That's how I got Ann Thraxx (in my profile pic), I just kept messing with sliders. I had a picture of some female tennis player (because she wouldn't be wearing makeup) but that wasn't working, so I just used the sliders.
