Inception's got some inspiring music too. So does Gladiator. If you write a poem to either of these, it can't be un-epic. I can guarantee that if you do math homework to Inception, it will seem like the fate of the world depends on what x equals.
I look at life all around me. The way the sun sets... The way paint is peeling off on some wall, the way the sun hits a certain building... The mountains I can see from my backyard... And concept artists, as well as looking at people's sketchbooks on conceptart.org. Some great concept artists: Feng Zhu Matt Rhodes Matt Barrett Kekai Kotaki Izzy Medrano Georgi Simeonov
My writing, drawing arn't really things that take beautiful inspiration to make. I think of something from the top of my head. Environment usally doesn't matter, and I go on from there.
