Boy Nursery

I liked the nursery potterybarn Preston, but my husband does not like it so much. Can you help me find ideas for a boy? I want something cute and unique, but not too crazy:)

We made the theme of the rainforest, but I guess it is not too unique because it has become so popular!
Here are some photos of Ryan Nursery

I also think a space theme would be really cool!
Or Snoopy theme was cute!

I did mine is navy blue and green material of Madras, with green and white stripes on the walls. It looks really cute ... but not too childish childish, so he can take if for a few years.
