Love the freehand mapping, and no, it's not too "vertical." I personally think we don't go vertical enough, which is a shame because it adds character and breaks up the interior sightlines for more tension and danger. I quite like your mapping style, too. It is uncluttered and clean, something I need to move towards.I've been doing quite a bit of freehanding myself lately, using oversized scrapbook paper of all things ... http://closetbarbarian.blogspot.com/2012/03/more-scrapbook-map-goodness.html
I love your maps, the one of Dunlyle is awesome. Great work! Adding you to my blog roll. ;)
