That's not a radial light, it's a reflection on the glass. The light itself is the same size as the window. Dark thing in the foreground is a rotting boat. Stones in the sand aren't so much "green" as they are slime covered. But, I'll see about doing something with that rock under the kelp. I had thought about doing something volumetric with the spots. How do you "fake" it??

Could be worse, could be raining.
