The Court of the Count is done!
The files with transparent backgrounds for this one are WebP files, as the PNGs were, as I expected, somewhat unwieldy. If there's serious demand for it, I can provide the PNG files as well, though I suspect most folk won't want to deal with files that robust.
I've provided a cobweb overlay that you can use in Foundry as an overhead tile so that when your players enter a room like the Audience Hall, where the ceiling is meant to be heavily obscured, you can have them pass under the canopy of cobwebs overhead - I do recommend turning down the tile's opacity in Foundry though, so your players can still actually see their characters.
I've also included a tile you can use for the light cast by the stained glass window in the Audience Hall, in case you'd like to build all the lights in Foundry yourself, but don't want to have to recreate that patch of color. I think that light was the only asset I had to create myself for this level of the castle, but it turned out to be surprisingly tricky to get to a point where I was remotely happy with it.
I'm going to start the 2nd floor of the castle as soon as I finish posting this to the usual channels, but I am visiting family for Christmas, so I'll be working a little more slowly until the 27th. Bear with me - we'll get there yet!

My maps are made with assets from Forgotten Adventures and AoA assets, and they come with grid/gridless and day/night variants, plus JPEGs or UVTTs and transparent layers for Foundry VTT.
