I’m not a professional mapmaker and I have no pateron, but I do love to do some photoshop kitbashing of the maps from various artists to get the feeling for the encounter I have my players going through.
In this case though, I really couldn’t find what I wanted for a fight in the streets of Gracklstugh. I’ve been teaching myself some Blender and came up with this. It features multiple buildings complete with roofs for invisible soldier Duergar, places for cover, and stalagmite/stalactite columns that hold up the roof of Gracklstugh. Sorry, no interior for the buildings, maybe later.
Hope someone gets use out of this!

The various building tops provide different height difference opportunities that don’t always show up well on a top down map. I’ve provided an animated video for my players to give them complete context for the map.
