I've gotta be honest, the map for the House of Lament really annoyed me. There's not a lot of detail provided, save the descriptions for the adventure, and something like six rooms in the manor are basically described as 'figure it out lol'.
Even worse, when I finally got to the basement level, I realised that this map seems to be guilty of the same thing the Castle Ravenloft maps are guilty of - that pesky 5ft drift. I wound up expanding the wine cellar slightly to account for the size difference, so everything syncs up if you're flicking through the images.
There's also the matter of the 'Mark of the Raven' featured on the top level of the old tower - this is only described in a single line in the entirety of Van Richten's Guide to Ravenloft, and it's not anywhere near its appearance in the adventure, so I don't know how DMs are expected to know how to describe it - turns out it's just a sunburst.
I've also made the roofing available as its own layer with a transparent background, in case anyone wants to use it with the Foundry 0.8.6 update, which I have yet to really try out, as I'm waiting on my favorite modules to update...
