Hello all.
IMHO the contrast increase is too much. You lost all the grittiness by making the colors more vivid.
I think that the adjustment needs to be toned down. If you look at the Church images for example, the after one is to violent on the eyes. It's difficult to focus on what matters. The shadows are much too strong.
However, I also think that the characters are too well blended into the environment. While I would dial down the adjustment of the environment (while still getting rid of the green tint), I would probably keep the new contrast for the characters if at all possible.
Looking forward to the game!
