I feel like one of the few people who... don't really care if a character is male or female. Sure, I like a little eyecandy from time to time, and I do get a little bit uncomfortable when it comes to same-gender couples in video games, but that's just something I have to get used to. Other than that, I judge characters on their motivations, convictions, personality, etc etc. That's why Princess Garnet Til Alexandros XVII is one of my, if not THE, favorite characters ever, female or no. The others being Sylvannas Windrunner, Arthas Menethil, Minato Arisato, and Fuuka Yamagishi.
Now, having said that, if the topic were to be what I find ATTRACTIVE in a female character, I'd be extremely opinionated. It would be more women like FFXIII's Lightning, RWBY's Yang, or... Well, Sylvannas Windrunner.
