Thanks for the four logo entries. I can certainly see where you are coming from and the idea has elements of things that I am definitely looking for. However, at the moment, the overall impression I get from the icon is not particularly visually appealing, at least at this stage. I am not sure how it can be moved forward either, while sticking to the same concept. The mountains are the part that I have the hardest time with. I like the river at the bottom. The relative scales of things bugs me a bit too but I do not see how to overcome that issue.
