Need some ideas! 56k WARNING

Hey!
We have a photoshop contest in our school, and I need some ideas on what i could do with this images!I only need like 2 of them. (:

They are big so it might take some time to load them.

1:


2:


3:


4:


5:

well i think you want to use either 4 and 5. And with then like a tech, furturistic thing.

1 and 2 could be used, so like the speaker exploding out of the sky and you could maybe add the guitar in there too.

Hope that helps, would go into more details but i don't know what level you are at.
