I like your hair straight -- nice color. Longer would be fine, but dreads? Hmm. Do what you want, but I don't think dreads would be an improvement on your lovely locks.
As for body modification -- tatoos, piercings... -- just know that you're making a deal with somebody you are going to be 5, 10, 15... 30 years down the road. He may have a very different opinion than you do on the matter. Really. And that shit's hard to rearrange if you get exotic about it.
