Undecided Question

I'm 16, live in England, and want to be an actor. I've been in many stage productions in leading roles, and I recently got an audition (final round) for a small British independent movie, to do with private schools, heavy drug use, raves and boozing (something like 'Skins' but even darker, more of a tragedy). I would be the completely messed up kid with a broken home who is very popular in school and with girls but who goes mental on nights out, high on cocaine and LSD, getting violent in the process. He dies somewhere along the way. Quite a major role. Like I said, not kiddie stuff, but could be a cult classic if done right.

Anyway, I'm up against about 4 other guys, and I need to make a good impression when meeting the director next week- I like to think I'm endearing, so I'm going to try to crank the charm up to 11. However, I don't know what to wear for the audition. There's a picture of what I was thinking of below. If you have any other suggestions, please tell me. Just make sure you know something about style.
Can you also if possible flick through the pictures and tell me if I look right for the role? I'm a good actor so I could easily make it my own, so make your judgement based on the look. Keep in mind that they want the film to feel gritty and realistic, so they don't want some Disney high school type guy with a perfect face. The character's not an emo, just a daring charismatic guy who gets into really dangerous situations through his own recklessness, slowly destroying himself through drugs. He doesn't see himself as a bad boy -charming in school, just as someone out to party (Think Cook from Skins, only more intelligent). Also, which accent should I use? I can pull all of these off well (remember that the character is very charismatic and shouts a lot)- there's posh, (this is a private school after all), there's normal English teenager (not too posh, more middle class, with a hint of chav or east end), 'mock'ney (like Mike Skinner from The Streets, the guy from Just Jack, or any indie band), or neutral. Any other tips would be very welcome. Thanks.

This is another possible clothing option:

This is in 'beauty and style' because of the 'what should I wear' issue.
