Rainbow over a Mountain Lake

A rainbow hangs over a still mountain lake with a clear reflection and pine trees along the shore.

The reflected rainbow and mountain shapes create a natural top-to-bottom pairing. Begin with the shoreline and pine trees, then match each reflection to its source rather than sorting all blue pieces together. Calm water has very few hard edges, so it is better left until the hills and bright sky have been joined. The details around rainbow over a mountain lake give the picture enough landmarks to keep the quiet areas from feeling empty.
