I like this picture because the photographer used the rule of thirds.
Setting the subject off to the left, this shows a more creative frame.
The photographer also caught the subect in the middle of an action, laughing. (candid. in action.)
So, in short, the photographer used their knowledge of off centering to capture a memerable photograph.
This picture isn't the best because the subject doesn't really fill the frame.
also there is no other elements to the photo.
no background.
very simple. plain and kinda boring.
just my opinions
