I've never smelled it, but I've found that some of the Tom Ford Private Blends require a dash of cold air to get them to liven up a bit. For example, I thought Tobacco Vanille was very nice when I wore it the first time just around the house, but when I wore it again and went outside to do errands and chores, it became a MASTERPIECE. To the same extent, I find Tuscan Leather to be a lot less harsh when you are outside, though it's still just okay for me. I can see why others love it though (you just really have to like leather).
Good luck with Oud Wood. I ended up passing on a decant of that in favor of NP. Hope I made the right choice.
