Photo synthesis

I am going to enter this photo competition. I've never done anything like this before, but I figured I'd give it a go. I can enter 5 different photos. I need your help to choose which ones!

I'm going to go through my photo blog and pick some, but I'd like everyone else to have a look through (please!) and pick their favourite/s, and post the link to it/them in the comments of this thread......because I really don't have a clue where to start. (Remember to go through the archives too!)

For some reason, I'm kinda excited about this. Maybe coz I haven't entered a photo competition before? I'll post the all the ones I enter here. Thanks!
