Pros:
+ Amazing level design.
+ Classic atmosphere that reminds me of Blackmail and Masks (but without annoying cameras and combat bots).
+ Enjoyable gameplay that keeps you absorbed and glued to the screen as you progress from one floor to another.
+ Interesting storyline.
+ Inclusion of additional zones within the castle (can't say much without spoiling) that make this mission more than just a regular mansion sneaker.
+ Fun and not irritatingly difficult puzzles. I have noticed a few completely original ideas, as well as the author's novel approach to ideas already known from other fan missions.
+ No bugs and no grammar errors in the readables (kudos to the beta testers!).

Cons:
- I would love to see a few more ambient loops in different sectors of the mansion. It's not that the sound design in the level is bad (because it is just fine), but this is only a tiny suggestion that could make it even better.

In my opinion, this is surely one of the best Thief 2 fan missions of the recent years.
