presentation boards

I need some help, I don't know how to do the background for the presentation boards. I have done a drawing but I don't really like it. And I don't know with images I have to put in it or how to do it.....

I don't know if is because I have been thinking in it for too much time.... tomorrow I will try another time!! Anyway, if you have any ideas about how to resolve it, please post something.

This is the drawing:



I'm thinking that it will be very big and the graphics have to be good... And another thing: I have bought the red clothe :D !
