Hey, i've been watching the development, and really enjoy the changes that maps go through. I think you've made alot of progress, and I hope that you are as happy as it seems the community supporting you is.
Overall I agree with the assessments everyone has been giving you. I actually like the overall texturinzation of your first map over the later maps. It seems to bring out the vibrant colors a bit more. As for the mountains, I think the best advice I could give would be to chuck em out and restart. Not because that they are 'unretrievable', but you've been getting so much advice and tinkering, I think a fresh start might help you get over that hurdle of incorporating everyones ideas. As for their look, the mountains look more like a moonscape pockmarked look, than terrestrial mountains.
Just a few ideas. Nice work though.
