I like long term, mature RP partners whose characters are unique. I dislike worlds immersed in magic but I can tolerate some elements of fantasy.
Throw away anything medieval or Renaissance. There's thousands of years and history an entire globe, I'm very much done with 1500's Europe. Besides I like modern day settings the best.
In my journal are some characters that I've used in other RPs. I tend to make a new one with each partner. My characters will never be big eyed, baby faced, big chested heroines who are beautiful and predictable. So forget blue eyes, weird colored hair, and the hour-glass figure. Sex appeal and physical attraction doesn't require such a generic description.
I can't think of much else to say. I also like playing dress up with my avvie, so don't be weirded it out if I change it every chance I have.
