This was a painting series and study project performed on twitch.tv . Waves of all colors and sizes. I used reference photos from all over the place. They are 8"x 10" on illustration board. The last painting is a 16 x 20" gallery canvas and includes a bonus mermaid.
Most of these paintings are still available for sale on my ETSY store. I have a series of aquatic life as well.
The paint I use is a good compromise between quality and value
