This happens on every picture. I'll struggle with 15, 20, 25 nodes, then create a new version, blow it all out and start over, then create a different look from scratch, using simpler tools. I then A/B the look to the point I forget which is which and look only at the hero display, and I stop flipping back and forth when I like what I see. If it's the simpler grade, I go with that and consider redoing the entire scene. If the better grade was the original, I stick with that and keep moving. It's rare that I can do it in one node, but I've definitely had cases where I go from 20 nodes down to 4 and wind up with a better picture. It may still need a little tweak, but better is better: I don't question why or how, I just want the results.
