OK, if you want.
1) very high noise of the picture (poor quality)
2) i'd suggest you to move camera to the left, so to give the children spaces to move
3) the stick (tube) before the boy is stopping his movement
4) diagonal composition is better than static (it is +)
I have a wife and 2 children and happy with them, but I do not think that my family photos (several thousands) would be interesting for you or others. If sometimes I'll make really interesting photo with my son or daughter I'll upload it, but now it is usual family album.
Thank you Nikolai ! I will use your advice wisely. I have looked at the photo again and you are right. The children are not mine , and my wife and I were off on a one day trip to photograph tulips. We came on these two with their mother just doing what kids do best . so I snapped the photo.
Next time I wil set it up right .
