Catching wonder

When I was snorkeling in the Florida keys when I saw a batwing sea slug swimming in the water column. I was captivated by how it moved.I wanted to show how I felt when I saw it but as the drawing process continued, it ended up being different. I first used markers for the original colors and then went over it with colored pencils to lighten it and draw the eye to the sea slug. The lighting is so bad in this photo, I will replace it soon.
