I actually referenced this backdrop from pictures by *FitzOblong[link] But snazzed them up just a bit with some gradients. I'm not sure what this location is, but the cool colours suited her battlesuit, and I assume fans will associate the scene with the suit.. I'm curious about what's through the green window..
You've gotta do what you can when you render Kim's eyes. She's unusual in that she doesn't have eyelashes to emphasise her femininity. She also doesn't usually have a highlight in her eye.. I would usually do some flecks of lighter colour but have to keep it simple when doing this style.
