Hi,
thanks for your submittal. I like the overall look, but the mountains look very alpine. We are in Hawaii, where the mountains look a little different and the valleys are where the settlements and of course the rivers are. Maybe try to make it look less alpine and more tropical. Google some images of Hawaii maybe to see what the tropical/volcanic landscape looks like. We want any mountains to be more subtle and in the background. Your current designs put the mountains very in the foreground, it looks kind of like a ski resort. Try keeping the mountains green and overall more subtle. I can give more feedback later today once I talk to my boss. Thanks so much!
