Very nice, and for me, definitely unisex. This doesn't come across to me as anything specifically (others mentioned patchouli, but at most there is a hint of it, relative to a fragrance like Michael for Men), though it evokes an abstraction of blueberries. I avoid top notes so I can't speak to that, but the drydown is fairly quick, and then it's rather linear, though it has nice dynamism in its abstract way. As Luca Turin said, it has an herbal/aromatic quality, but the tonka/sweet qualities are quite strong, so it's not the kind of herbal fragrance I'm used to. It took me a while to enjoy it, because at first I didn't want to smell blueberries for several hours, but after wearing it a few times, I was able to appreciate it beyond that aspect. Sillage and longevity seem moderate to good.
