So I decided to give hatching a try. On paper, with the right kind of pen, I've managed to produce some tiles that I'm really proud of. Alas, completing the following tile with my drawing tablet doesn't look quite as good (and it was a pain in my wrist to boot). Oh well, it's a start. I suspect that I'll be evolving my own technique as a complete more of these. It may be that I just end up switching to scanned hand-drawn maps.
Anyway, for this tile I went back to White Plume Mountain. You really do get to add more details on these sidemorphs and for this one I added a gargoyle, some kind of altar, a pile of gold under a lantern, and a drainage valve at the bottom of the lake of hot something.
By the way, I also experimented with a higher resolution on this tile. I'm not sure it really added anything this time.
