Great to hear you're on Patreon now John. I wish you all the best with it. In my opinon, If someone should be freed from the hardships of commisioned work to let the remarkable talent and creative juices flow freely for the greater good, it is you!
The Palace has so much detail and character and it seems to fit perfectly next to your Umi No Toride Castle map. I love that your maps have this great balance of detail/charme of your personal style and playability/functionality and to me it seems perfect for roleplaying games.
