Your regrade mildly adhusted.
The yellow I think is correct don’t fight it. Blue might be the problem. At the end of the day do what you like. I have no objections to the color. But this I think might be closer to what it is “Meant to look like” taking in to account the problem with the dark grain and how it’s smearing the wall blue. It might also mean this guy has a grey jacket too 😃
Just trying to be helpful. I am not asking you to change it.
You went a little too far. The jacket is suppoed to be more of a slate gray and the shirt light blue.
