Thanks @theluthier I love this kind of constructive feedback. I made a few different printouts of the compositing and came up with 3 promising results that all looked similar but had varying levels of contrast and darkness. I’m still new to compositing but this was actually one of the really fun parts.
This was the darkest of the bunch that definitely had a black hole and my wife said that she liked it best. I was trying to talk myself into how sea light tapers off quickly due to light absorption/refraction, but I should have studied that more thoroughly. Your explanation really helps though. You are correct. The transition is too harsh.
Part of this had to do compensating that I was struggling getting the rays to work exactly how I envisioned them. They were very finicky which just means that I need more training on how to make them work better rather than just toying around in the fog or my on ignorance. But I did learn a lot on my own!
I went back to research a little more and this was what I was trying to get at but I was too aggressive on this render.
