The third set is now available! Here is the Beach Series:
The set includes 4 coasters which are all Beach themed.
Coaster 1. Night beach with low moon
Coaster 2. Night beach with high moon
Coaster 3. Sunny beach with green in background and calm waves
Coaster 4. Sunny beach with waves
They are painted on 4x4 canvas boards and are sealed front and back to ensure water can't get to the painting. I would not recommend submerging them in water, but they are safe from condensation.
I did not record this series, but I was live during the the paintings. Here are the live videos:
