Though Flesh Be Vast - Map Preview

I'm about to release an adventure for August, but while I'm still wrangling with the text, here's a preview of the map.

This one's a little different, it's a two-page map spread.  A series of natural caverns gives way to an underground settlement, with roads that extend into underworld areas beyond.

I'm experimenting with the use of old-school style blues grid lines to convey the scale. I'd be curious to hear they're useful or just distracting.
