Really nice. I'm looking forward to getting deeper into the lighting side because of stuff like this.
Good job, I think the light could be forward more. You can see the reflection on the front of the forehead, suggesting the light is in front of the character rather than above. This will also brighten the face area to match.
Well done 👍
Really good results here gglenng910 ! I think you nailed this challenging exercise. My only suggestion would be the same as Adrian's - experiment more with bolder colors! I would stay away from using a full saturation of 1 but anything even slightly less than that is fair game. Keep up the good work 👏👏
