Yeah, this is not the final result. I am still in the midst of experimenting in photoshop to create the effect of light shafts in water. I was planning on doing it with paint, but before I tried that and potentially ruin the painting, I thought I'd give it a digital shot.
As you can see, they don't really work. The first one uses five spotlights, and the one above uses a blue omni filter. Looks really cool, but not quite the effect I was going for. Below is close, tweaking the spotlights at an angle. After working on this for an hour and debating with both Craig and Lady R in New Zealand. We are a bit stuck. But Craig did manage this effect above, literally making pikaia god of all things Burgess!
