I used your gradients but i have been blending my own colors in where i feel they need a boost. On your temperate gradient, the brown really came out looking bad on my map. (probably because i set the bump map depth too high.) The parts of the mountain that would have been brown ended up really grainy. I might have to give it another go in Wilbur and try and erode down some of the noise. My issue is it looks good in the desert, but not so good on the mountains.
