Unicorn by a Rainbow Waterfall

A gentle unicorn drinks from a pool beneath a rainbow waterfall surrounded by flowers and smooth stones.

The waterfall and its rainbow make a bright vertical centre beside the unicorn's curved neck. Smooth stones and flowers create small groups near the pool, while mist softens the far side. Work from the water's edge outward so the magical colors stay connected to the scene rather than becoming isolated patches. At higher piece counts, unicorn by a rainbow waterfall gives you enough texture changes to keep the final section interesting.
