Great review! I noticed the Musk dominated the first third of the perfume, while Oud stood out more in the dry down. I had a hard time finding the rose myself, but felt that I caught it a few times. Seriously, the first hour for me is loud. I enjoy it very much, but much prefer the heart and base. I find it easier to wear once it calms down it a bit. I believe the musk will macerate well with the ambergris and blend very well with everything. I get 14+ hours.
Has your viewpoint changed on oud royale? You don't seem to like it very much in this video. I am thinking about buying this but can't find any reviews, let alone anyone who talks about the scent profile.
It has gotten better for sure as it settled down since I obtained it. I very much enjoy the rose and oud note in there now. The musk has also become increasingly pleasant and enjoyable for me; granted my nose did require some time to get accustomed to the it. Hope this helps.
