Need help trying to figure out what is wrong with these images. And why they were rejected

I looked at that image at 200%. I do not know how I missed the mangled hands. Thank you for pointing that out. As far as the too-similar rejections, that is what's really getting me because I am checking them in the search, and I'm not finding anything like my image. I just don't know how to handle that. I'm changing the keywords around, and I am even looking at briefs for needed images. 

I missed that logo. It would be a good thing to remove. I appreciate all the comments everybody gives me here. Really helps not to be so frustrated. I don't mind her braids, and the boy is supposed to be looking at his phone. I just felt he was interacting with the rest of the group.  And I personally feel that whiter teeth wouldn't look natural. I will take all of these comments and put them into the Gemini generator and see if I can get the picture accepted with your comments. It was very difficult getting the laptop to be in the right position with the mother. It kept turning it around. I don't understand why the generators aren't listening to the prompts. My prompt was: Turn the laptop to face the mother,And it kept turning the laptop toward me. This was a very complicated picture to put together. I also gave up on the braids. My prompt was to put the braids behind the girl's shoulders. And it kept putting them in front of the girl. Do you have a better prompt to get them behind her? When you work on a complicated image like this, your mind doesn't see things like other people do. I appreciate all your help. 

Thank you. I missed that. Gemini did that. 

The other one.

A few things.
