As an experiment I'd try coming up with an idea and then executing it. Like, ok, I'm going to make a three-headed giraffe in a pool of acid and then just go for it! I suspect you might be just opening a new template and layering images without purpose. Some designers are excellent at this... just designing on feel, but most aren't.
I've done the full bleed blend a couple of times now and always like how it looks. It helps to have an incredible printer like D&L too. The fireflies glow in the dark and this image was a collaboration with Kristie (my wife). She's 7 months pregnant now but still made it out to the Austin show with me... whoo old people date night!
