I’m not digging the grayish sky. It blows out and it looks like you tried to put something in there. It’s a little hazy overall. I’d try flagging the flare in the lens off a touch. I love the flare coming off the arm camera right. that is very cool.
Second one, hands need to relax a little bit. The density is better on this one, I think.
Third one is way different than the rest. different color, tonality, etc. It kind of doesn’t fit that well. It is far more saturated than the rest. I would try to bring a little warmth into the two above. Overall, better though. I would actually suggest getting a little fill in the face. They seem very down compared to the background. At least on the first two.
