I'm usually the other way...I start out making everything too small and that makes things take forever so after a few hours I scrap it all and go bigger. Lather, rinse, and repeat a few times. I usually do about 6 or 7 different mtn styles before I'm happy. So, yes, hand-drawn style maps can take a real long time if you're picky like us...and makes me insane and burns me out.
