leovyner: There are many definitions of street photography, its up to the photographer on how to interpret them. Each street photographer has its own style based on how he interprets the meaning of street photography. But basically, my interpretation of street photography is "recording everyday / unusual lifes of people in an area inside the city or suburb". It must not be staged, I won't ask permission for photos so its best to be stealthy and avoid standing out in the crowd to get photos! =)

I like the 2nd pic. It shows that the 2 kid is running with enjoyment towards the park. But as yuhi says, it could be better if the subject (kids) is more dominant/stronger
