The colour one looks great. Is it Clercon's style from the annual thingy? I like the brown one but I don't think you've got it quite right yet.
For instance, I don't like the patches of green with the blur around the edges on the brown one. That big computery blur doesn't fit in with the style you are shooting for imo. Whereas on the colour one it fits in just fine.
I prefer your labelling on the colour one too.
I do prefer a more destaurated, hand-drawn style map myself and I think with some modifications I would prefer the brown one. But for now I'd vote for the colour.
