Well, I have her envisioned just a little different as a rebooted character. For one I've recently taken to drawing her in a leather jacket, like AJ having a stetson now. Not telling you that your revision has to match mine, but feel free to have a look through my gallery for inspiration!
BTW, I play Firefly on Secondlife in MLP SIMs. My gestures are sound bites of Firefly in the G1 Pilot. My favorite ones that I play maybe a little too much: "Danger is my Life!" and "My names Firefly. What's your's?" X)
