One of the first rules of writing is "Show, don't tell". You told, you didn't show...I have a laundry list of your likes but no idea how that relates to your personality...just like most of the other people on these kinds of sites. The "singing badly when nobody's around" part is actually great...it conveys a couple things, you have a self-depreciating sense of humor, are honest with yourself about your singing ability but you do it anyway. That shows more who you are...try throwing more of your personality into it like in that example. You've been alive 20 years you've gotta have more to say than I am quiet, outgoing etc. Or better yet...write it like you'd describe it to a friend.

In the end it doesn't really matter, though...a lot of people are shallow and most won't care what your interests are or how you say it as long as they find you attractive. I just know from a reading stand point it gets boring as hell when I read a chick saying she has a great sense of humor (or what not) but never proves it by actually being funny.

Anyway, there ya, go...a little constructive/creative writing criticism from a guy that digs writing.

Good luck, darlin'.
