I'm torn on the lighting.

On one hand, I do enjoy things like the chapel and tomb being a little more well-lit, since there is some sun coming in. The outdoor spots look fine to me, except yes, things like the goblin camp should definitely be more dark and grimy to give that specific impression of the environment.
However, in spots that are underground with zero lighting (ie. The Underdark), it should be almost pitch black.

Give me a reason to use my Darkvision and Light/Dancing Lights. If players complain they can't see, then that's kind of their own fault for
A) Not taking Light/Dancing Lights (Which are available to both Shadowheart and Gale)
B) Bringing a torch or two along
C) Bringing Astarion along

If people STILL complain about it, simply add an item to the game that provides the Dancing Lights Cantrip. Solved.

And the hair.. OOF, the hair.
I've created quite a few characters since Patch 8 dropped, and I can't find a single good redhead or blonde colour. It seems like all the blondes have gone gray, and all the redhead colours have gone pink, or literal orange/red. Nothing looks natural anymore.
