I would have to lie to tell I'm not wow'ed. The art is amazing, the idea for ingredients is really great - there's more stuff to find than just the things party is sent to look for, I'm sure any player who wants to dabble in alchemy themselves will have a lot of fun.
The module is really open ended, and highly modular, by which I mean - it's easy to drop into an ongoing campaign. A quality I highly appreciate!
Layout is good, I really like that the background and all information necessary to introduce this module to your game is clearly presented at the beginning, without any attempts of mystery. That's good. Mystery is for the players.
One criticism I have is that I wish the dungeon itself had more ways to enter or to approach it.
