The first has a noise issue and is slightly underexposed.

I agree with Jacquelin on the white balance issue.

Your second also has a small white balance issue. The main problem here is the black clipping.

When doing portraits, I'm not for overly correcting all things, but I think, you should really correct pickles.

(that's not a refusal reason, however).

Hello,

In my view, you should correct the white balance in all of the photos. The skin tone is wrong. There is a green cast to all 5 photos. The skin colour looks somewhat green.

E.g.

 Something like this might be better:

In addition to the technical issue noted by @jacquelingphoto2017 you would also have needed signed model releases for each person in the frame.

GabrielTrujillo_Manifestacio 2023_179.JPG - the entire sign and hands should have been in focus. Depth of field too shallow here.

Hi @Gabriel Trujillo Tf,

The first file has a slight green white balance issue. Correct that and you should be good.

I'm not sure what is the issue with the second one. The hair comes across as being grainy, but I don't see it in the dark area. You could probably take down the highlight a bit, not much. 

The third file also has a white balance issue.

There is a halo around the edge of the man's shirt sleeve in the fourth file. I believe you could have included more depth of field to include the second row of people since their plaque card formed part of the subject.

Details are lost in the shadows of the fifth file and also there is a motion blur.

Best wishes

Jacquelin
