It’s looking really good Brandon. The lighting is great, the tone is a bit much sepia or yellow for my taste, but that is personal preference more than anything. To troubleshoot the wave problem you notice, I’d start by adding a test camera that I can move around closer to the objects with said problem and do some test renders, just to see things up close and from other angles. Usually you end up discovering that it’s too much bump interaction with the light and hitting at the angle you have set up, or maybe it’s the denoiser or just some artifact of the resolution. Either way it helps to see things up close and from different vantage points to really see what’s going on first.
