Hey there, you did great on this assignement, though there are still a few nitpicks. First, in the first exercice, they all are very close, maybe try shift a tad their hue and brightness. You nailed the first picture on the second exercice, But the second one's colors are a bit faded, the sky and the suit are the most noticeable difference. For the color balance, try to crank up the red. (Also the reference picture have some weird stuff going on there). And For the last one, I struggled with this one too, so I can tell that it is close, but I don't know how to fix it. All in all, it's great ! 😃 Have a nice day! (And please don't be discouraged)
