Yes, that's right, it is time for me to get my hair chopped! Last time I had to do it myself, and I've had the same cut 3-4 times in a row now... so I'm ready for something slightly different. Hopefully something that doesn't poof out into the perfect Beatles bowl cut when it air dries. (and sorry for the number of images, ahead of time)
Of course, for reference, current picture of me:

and my head in profile, which I am bizarrely really self conscious about. Which is the #1 thing that makes me worried about haircuts (other than passing in general).

Any suggestions you have are good, but I have two thoughts.
1. simple change, just shorter on the sides than I'm used to:

2. Radical change, modified mohawk (shown here on a girl, technically... but I love it)

Mainly I'm worried about how I'd pull off the mohawk... attitude wise I'm fairly confident and artsy, so it's more a matter of would I look ridiculous. And any other suggestions, even if they're totally out there?
