Undercuts - not really body modification I know, but...

I didn't know where best to put this thread, so yeah sorry if it should be somewhere else...

Well anyway basically about a year ago I started growing out my mohican on one side. I am now left with shoulder-length hair one side and the other half shaved, except for about the top quarter. I grew it like this because I loved having short hair and long hair and couldn't decide which, so got both

Another reason was because I wanted something more versatile than a mohican, I missed having ponytails and plaits and bunches etc. I'm wondering if anyone has any other ideas of what would work with an undercut? I'm feeling experimental and have run out. Ta
