Your figure - more precisely, your waist; you have this perfect hourglass figure, and it makes you seem feminine in a way that somehow also in myhead means you're several inches shorter than I am, despite the fact I KNOW IRL you're roughly the same height.
Wrists. Don't ask me where the hell this came from, but in my head, you also have really slender wrists (and ankles, but you also normally are clad in stompy boots, so they pop out less).
Your laugh - not technically a physical feature, but the manner and gestures you make when you laugh - head slightly thrown back, you never ever laugh with your mouth shut, your lips always part at least slightly, even if you're doing that thing where you laugh through gritted teeth, and is very attractive when you do. (Laughing in general that is, not laughing while pissed the fuck off.)
Jawline, it's not heavy in anyway, before I make myself misunderstood ^_^ It's both feminine and defined, and it somehow compliments your mouth, which is kind of...rosebud ish? Ok, it's not, but that's the rough sort of shape, and your lips have very good colour.
Also, your eyes are very blue ^_^
