To show the results, I attached two images, one from the original base set, and one from the zbase. It seems to me that the brightness of the less-snowy flat tiles is too high.

It looks like the issue is with just the steepest slopes (i.e. corners raised 0, 1, 2, 1). These sprites will need serious revamping at some point anyway.
