i can see you and your suburbia in the reflection on the bubble! :) i love this shot. i take ones like this all the time with my children. getting the moment when the bubble is blowing is hard to do! i like your crop, also.
Good idea for this challenge It's cool that you can see a reflected scene in the bubble. I don't know that the boy adds much to the photo. I would have tried to get a version where you cannot see him in the frame.
