Hairstyles

So, a conundrum. I've had long hair (past my waist) since forever. I cut it once in 6th grade, a bob that ended at my shoulders, and it emphasized the fact that I kind of have a bit of a turkey neck.

Anyway, I want to do something drastic, something preferably really short, that won't emphasize my neck or anything like that, but I'm perfectly awful at knowing what looks good on people and what won't (as evidenced by the Horror of the 6th Grade Bob).

So, any suggestions would be awesome. Thanks!

Included are four pictures of me:

This was actually posted to a comm, so excuse the formal nature. Ideas, suggestions, cautions, my dear friends? I'm hoping one of you is a closet stylist, so help me out here.

I think I want something kind of punky, because I'm going to put green or blue streaks in it, but I'm up for suggestions!
