Like the ideas.. can you please try to incorporate community and perhaps children too? But overall great start. We really like how you have taken the idea and shown us how it can be used in several ways - that would work for printing on various kinds of media ...
I feel like the "people" do add to the idea, but the one without has stronger graphic quality - the people and more bubbles makes it "busy" ... can the people stay but keep the strong graphic quality of your "first" try.
