Hi Suke,
my boss is looking for something different-looking. The mountains are too shaded and 3D-like. Try something like #36, but with a totally different style for the mountain. Be sure to add a village alongside the river. This should not be actual houses, but dots and lines suggesting a village, like you see from an airplane. See the air photo I attached in the contest brief. We are reviewing again with our boss in 5 hours. Thanks!
