I can understand what the OP is complaining about.Look at the boy's jacket on the right shoulder. That's what the OP complains about. It may be good enough for you, but I can totally understand when OP is coming from.
But you have to understand this photo was done on a mobile phone, in a corn field, chasing an excited 5 year old around.
The moment was there, I took out my phone and snapped a great shot. A blurred shoulder isn’t going to ruin the photo for me.
To do the same on a dedicated DSLR would be far too impractical for me and time consuming.
