Photo Exhibition Help!

[kneeshooter]

I've been invited to put some photos into a small exhbition in Shropshire - proving it's not "what you do" but "who you know". So, I'm after some suggestions of what are my most saleable pieces - to a general rather than muso audience.

So, I need help from all my friends list in picking out four pieces that might both show off what I can do, and what might sell.

Help!
Please!?
