Nice job with this! The layout is great and consistent with the ItO style. Because you mentioned you wanted feedback/critique, I will say that this adventure feels a little low on gameplay and interaction.
The rooms encounters are a little obvious and passive in some places (e.g., the lobby and landing don't really act on the PCs). Also, the pantry says there is a 50% chance of a "simple trap" but the description doesn't say what the trap is, how it works, or why it's interesting. I think it would be better if the trap were specific and were guaranteed to be there for more interaction. Finally, the dungeon is pretty linear, with one room after another in order (with a locked room off to the side). This doesn't leave much room for player exploration.
