Thanks for the compliments! It was fun to draw and try to move the style of the cave maps on to an outdoor setting. I can already see a few things I want to try next time. We'll have to see how it goes.

@Neonknight: I'm sure I wouldn't call it a work of art from beginning to end. The beginning sketches were really ropey

@Sigurd, I used Gimp for the whole map. I sketched with a 5px brush for the first shots and then used a new layer to ink carefully over the top (2-3px Ink brush in Gimp). All in Gimp with a Wacom Graphire4 A6 tablet.
