One-Page Dungeon: Grid Update

Got stalled on this due to needing to make some decisions. Things like:
- Will room descriptions be written directly on the map or in a separate key?
- How will I add a grid? Do I even want to add a grid?
- What kind of texturing can I use for the negative space?
- What format and layout do I ultimately want for this?
- How much customization or detail can I include in the map features?
It all got a bit overwhelming, so I took a break. At this point, I think have a much clearer understanding of what I want. Starting with a hand-drawn grid, and some simplification of the map.
