Looks-wise, as everyone says, you're a total, 100%, super-pretty pass - you're MUCH better looking as a girl than a guy and you've got a very sweet, feminine smile, too.
The only remark I have, and it's intended as totally constructive advice, is that you should try to put a bit more intonation and variation of pitch into your voice. One of the main differences in male and female speech patterns is that guys tend to speak in a monotone, and emphasise a point using volume, whereas women speak in a much more up-and-down style and emphasise with pitch: going higher to express intensity, rather than just louder.
Since you're a musician, heres's a simple, if old-fashioned comparison. Think of the Beatles: specifically, the double A-side single Strawberry Fields Forever and Penny Lane. Strawberry Fields is a Lennon song and, like most of his mid/late Beatles stuff, the melody line is pretty much contained within a very narrow range: that's like a guy talking. Now think of Penny Lane, which is a McCartney song, and, like most of HIS stuff is much brighter and bounces up and down the scale: that's like a girl.
Right now you sound Lennon. The moment you sound McCartney, you'll be as passable with your voice as you already are with your looks!
