Cant get over how awesome this area looks. Not too sure how to get rid of the banding in the sky around the rainbow though. Still learning how to take good shots, advice would be appreciated

Those recent Blood and Wine shots though... what's with the ridiculous saturation? Looks like a Disney/Kinkaid artwork lol
Not sure about fixing banding but lowering saturation might help.
I think overall though your palette just needs to be a bit more simplified. You currently have Reds, turqouise, blues, oranges, greens all trying to compete at 90+ levels of saturation. You can go highly saturated if you like, but you just need to balance what colours you want saturated and what ones you don't. Same goes for levels (how bright or how dark parts of an image are). You need a balance for your foreground middleground and background.
That said, even aside from sweetfx tweaks, I'm personally not really a fan of the colour grading in the Witcher. I think it's kind of tricky to fix short of just desaturating it, as it's not like you can have a different sweetfx profile for every area and time of day in the game.
Here are some ideas for balancing out the saturation.
Don't take my comments to heart though, remember I'm just some internet random.
Keep up the screenshotting homie!
