How to decorate a boy's room...

I'm searching for inspiration... again!  This time I'm going for a non-cartoon character look and although I have a fair idea of what I want to do, I have a zero budget so will be using what I have on hand.  Can I do it?

I like that red, white and blue looks fresh but is it too patriotic?

This look would be easy to achieve but it would mean a massive cull of Elijah's toys

Perhaps a cluster of his baby photos

Along with a display of artwork

I'm open to ideas so if you have any thrifty ideas let me know (please pretty please)
