Opinion's Please!!

I'm ready to start working on setting up and decorating Benjamin's bedroom. I want to make it cozy and inviting, but simple and not over-stimulating. I'm planning on using navy and cream w/ some accents of cranberry red and maybe a little hunter green....you know...boy colors! : ) I want to use stripes and maybe a little plaids.

The problem I keep coming up against is what theme to use to decorate. Whatever theme I choose, I want it to just show up in a few accessories or artwork, but not be too much. Nothing seems to grab me yet. It was easier to pick a theme for a baby nursery, but for a two-year-old that I don't know yet it is more difficult. I don't want anything that could be too scary or unfamiliar to him. It's hard to know what might be meaningful or what he might enjoy.

Here's some thoughts that I've had:
1. In the most recent pictures we got of him, he was holding a matchbox car. I have been considering doing a car theme.

2. In some of the photos of the orphanage that I've seen, there are Winnie the Pooh paintings on the wall. I've never been a huge Pooh fan, but I like the idea of choosing something that might be familiar to him and soothing. I'm not sure though if the pictures I'm looking at are the big kids orphanage and not the baby orphanage where he is at. I was hoping maybe some of you who have been to Liberia might be able to help me on this one. Would Pooh and friends be familiar/comforting?

3. He also had a Mickey Mouse on his t-shirt, so I considered that as well.

I read a hilarious story on one of the other adoption blogs I read about a family who painted Nemo on the wall of the bedroom for their adopted son. They found him staring at the wall and asked him what he was looking at. He told his dad with longing in his voice, "I wish I could take that fish off the wall and eat it." Heeeheee.....This is what I'm trying to avoid....choosing a theme that might just make Benjamin hungry.....or evoke an emotion that I didn't even think about.

Whatever we go with it will be very little, just enough to be fun and dress up the room a little bit. So I'd love it if you'd leave me a comment and tell me your votes/opinions/other suggestions????
