Spread flakes out over 5 layers now (far back, mid distance, just behind land, just in front of lands and hog, near distance). Spread clouds out over 3 layers (far back, mid distance, just behind land). Add a flatten clouds option, use d on Underwater. Alter some flake PNGs to reduce variation in size since scaling is being used.
