Hey, this is the 21 century, we use color photos now.
But she is definately cute. A little too much mascara on the eyelashes for the picture, but she's a cutie. Here's what I have to say:
1) Don't be nervous, be yourself. You do that all the time and you're (well, you shouldn't) yourself all the time without being nervous. The presence of an individual should not affect who you are. (Even though we, as a society prove this point wrong.)
2) Since you are leaving soon, it seems kinda silly to maybe start something that will come to an abrupt halt in a few months. Obviously, you will be returning, but a 1-2month relationship is not a great foundation to keep something going while away.
3) Get some pics that show some more skin...if you can.
