I don't know where the right place to ask about hair styles is, so I'm asking here.

To get things kicked off, my hair can get sort of thick, and fairly curly. For the greatest part of my life, I wore my hair really short, like this: http://imgur.com/Eo9jJ. Recently, I decided to allow my hair to grow out long(ish) again. This is the result: http://imgur.com/9i0nX and http://imgur.com/6TYT1. My question is 1) Whether or not I should keep my hair long like it is and 2) What other styles can I pull off with the hair that I have now? Thanks in advance.
