I started working on two paintings to complete a series started with Queen of the Night Sky and Fallfire. I hadn't planned to make the seasons, but most people assume that Queen of the Night Sky was meant to be winter, and I've gotten a few requests. Spring is cherry blossom based and Summer will have a sun motif added to match the stars.
Below is a mock up of my planned colors. They never end up exactly the same in watercolor but it helps to know what I'm doing first.
