Ages ago i entered some work into a arts and media festival: http://www.noisefestival.com/
It was used along with many other student's work from around the country in the main flyer adverting the event, here is the festival's final poster where you can see the 'Dead Tree' picture I made on the left hand side right underneath where it says 'Noise Festival.'
Below is the chosen 'Dead Tree' picture for frame of reference.
