It certainly sounds interesting, especially the real ambergris.

I can handle patchouli if it's not dominant, but it's actually the clary sage that worries me. My experience with it (which is mostly in essential oil diffusion blends rather than perfume) is that it's too dirty of an earthy note for me. It's not a clean dirt smell to my nose, if that makes sense. But of course perfumes are different.

Ahuizotl sounds like it has some things in common with the old BPAL scent Seasons of the Inundation, which I liked a lot although it was a bit too odd to wear often. SotI centered around wet earth and petrichor; BPAL then put myrrh in it, which didn't quite work IMO. It sounds like Ahuizotl is making a more interesting choice to not sweeten up the scent.

I look forward to hearing what you think of it.
