Worked on another isometric dungeon drawing today. This time I used Papazotl's Shrine from Tomb of Annihilation as inspiration. Of course it's very minimalist, but I figured this was good practice for perspective as I was forced to create each of the small half walls around the outside.
I'm relatively comfortable at this point with getting something that works spatially, even if my lines could use a little cleaning up. I think my next one I can start experimenting with adding a little detail and character.
