I dont see much interest in these. They are all pretty small, so its hard to see if these are actually sharp
1- Would of been improved if you were much closer in on the kid's eyes, but kept the hands in image. Too zoomed out for my taste. There is too much head room on the top
2- Just a continuation of #1, so yeah, pretty much same CC. The face seems under exposed
3- Meh, again too zoomed out. Too much space in the back, too much space on top, not close enough, dont see any eyes or faces, the image is not straight, dont like the ref blocking part of the frame. Comes off as someone standing straight up on the side lines pointing the camera nice and square, no zoom, not much thought, and just hitting the shutter. Actually, might not even be the sidelines, might just be from the bleechers.
You really need to get in closer to the kids to capture the moments and expressions. Shooting from far out like that just isn't too interesting. Dont get me wrong, I'm sure they make great life snapshots that are fun to share with family and friends, but I dont see them as photographs..
Your signature lists a 75-300...where you using this lens?
