This was a favourite drawing I did at Sketchfu, I can’t remember if it was a challenge drawing or just something I decided to copy because I liked it so much. I enkoyed trying to show the sunlight penetrating down through the water and catching the Orcas back. Its a bit sketchy but not too bad.
Water changes the colours you see, and the deeper you go, the more towards the blue end of the spectrum the colours become. Reds and yellows fade away as you go deeper, until the blackness in the depths of the water absorbs all light. It is at those depths that you start seeing the dim glows of Angler fish. I actually think it would be fascinating to go down in a submercible and to see some of the otherworldly wonders, but I dont think I ever will. But I can use my imagination…
