To be honest, I'm not entirely sure about whether scaling it down helps. I had bit of trouble figuring out how Tear got to his final version, 'cause when I tried to follow his tut by the word, I got something close to what you have now. I asked him if he had scaled the Saderan map he posted here, and he said yes, slightly.

But while his tut is great, you don't have to follow it slavishly. The map that I'm currently working on, for instance, (http://www.cartographersguild.com/showthread.php?t=8510), takes some of the steps from Tear, but the "peaks" are just plain white color, not a pattern, and the grass is just a green color with some noise and a blur, no pattern overlay.
I think the mountains worked out pretty well, I might changed the grass, though.
