Carte Blanche

I am designing a master bedroom for a single elderly gentleman... though I don't know that he would like me to be calling him elderly. But since he is older than my dad, he falls into that category in me book. He's a great guy though, and is giving me a really exciting project. I don't have many boundaries on this one, he just wants it to look good. He says he's a chamillion - he can blend in with anything so there is no reason to try to make it look like something that he would want. Make it stylish. I did get him pinned down to something more modern. He has some sentimental furniture, but then again, everything is sentimental in the house - one of the reasons for bringing me in was to break through the sentiment. The furniture can stay or it will go to his children. A real Carte Blanche. In a lot of ways this is really cool in other ways.... some direction/feedback please?
These are a few ideas that I have come across that I think would be appropriate for a client's bedroom.
I am leaning toward neutrals/browns with bold patterns in accent. We discussed keeping the existing furniture so I began designing with that in mind. However, I feel that the furniture that the client has now is more traditional and has more feminine curved lines than what we discussed for the overall desired look. Since the client is wanting a modern, masculine feel I have suggested that new furniture be brought in. I have suggested that the senitmental furniture be used in a guest room, and the client seems pleased with this alternative. Below I have included some concept photos, Renderings will be comings soon and photes when the project is complete. These pictures definately need an accent color, I am leaning toward red and/or gold, there are some middle eastern artifacts that the client has requested to be included in the decor.
