While this could be a good image your sky ends up ruining it. It is difficult to shoot from the shade into the sun, most cameas have a bracket function, check it out and see if a different exposure and maybe a flash could have helped this. A circular polerizer may also helped reduce the brightness too.
1. Tonality/range. Your subjects are in the darkness and the sky is washed out. Better to take pictures into the dark than to lose them against the sky
2. Doesn't have a clear subject to begin with. If you're going to make grandpa the subject, make sure that that is clear in your composition. Likewise for the boy, but If he is the subject, then he nees to be closer in the frame, or have much less distraction (fence, grandpa, sky, house)
4 just to be sorta nice. Not trying to be to harsh, but I hate when people vote me down without telling me why, so I thought I'd tell you.
