My comments or suggestions below are not a criticism of you, your model, your talent or skill. I offer them in a friendly tone of voice and with the sole intent to help you with a second POV and set of eyes. If you read sincere questions and simple suggestions as "criticism" of you, then you will miss how I am trying to help you. All smilies I post are genuine and sincere.
Of course this may be your own "style" or your own "vision" and I suppose we can assume that the images look just like they do because that is exactly how you like them. That is OK too. It just shows that there are differences of "opinion" on what looks good. IF these are exactly what you want and like, then by all means continue making your images look like that and have fun doing it. As I always say: "Follow your own muse."
From my comments on your earlier mega posts, I hope you remember that I think you have made many fine photos of kids playing and having fun. Some were exemplary images!
From this set the only one I really like is image 3.
I think the others could use better framing/composition and moments.
Also, the POV seems about the same in many of them...(looking down on the back of a head) and I found that repetitive and lacking eye contact and so...not as interesting to view as other photos I have seen you post.
Also, if you were using a camera with a waist level finder, I think LOW POV would be a good thing to try for something more unusual to see.
I hope these honest and QUICK comments help you.
