Crestock.com is having a photo design contest. The rules are wide open:

For each round we will supply a set of source photos from our image library. Your entry must be based on one or several of these photos, but you are free to do with them whatever you like. You may also use other elements in your design, as long as one or more of the source images can be recognised as a central part of your design.

First round here are the images

If you’d like to vote for my entry you can do it here:

I’ll post the winner once it’s announced.
