For the lower right room, you could always have it descend below the level of the southern hallway - so it's layered beneath. You'd need stairs down into that chamber - or stairs up to the southern hallway - but you'd give the map a little bit of variety in 3 dimensions.
Looking good Erik. I found once I'd got about a dozen I could start putting them together to make dungeons and then draw more to fill in gaps. Just drawing bits of maps is a great way to generate ideas too.My next Kickstarter should be starting in about 1 week and will be for larger A4 and A5 pads. Here's a preview link but it still needs a few tweaks and some images: https://www.kickstarter.com/projects/1730454032/1676796981?token=b770aa51
