Decorations for a "Guys" bedroom

Below are a few paintings/decorations I did including a NYC (Jets themed) skyline painting, a bull painting, a bear painting, and a wall collage.  

Wall collage: 
I scoured thrift shops all over Manhattan to find masculine/affordable/unique pieces of art.  I added to the collage: a painting of my own (bottom right), a photo that I took of his lake house (bottom left), and a photo of us walking from behind on a beach where I copied and altered the colors to make an Andy Warhol type piece (top left). I would love to add paintings to cover the entire wall eventually.

Which one do you like better?
