here #56 and #57
I changed the colors, and i also added a larger wheel vs smaller wheel to give it a more motion feel.
Also, to make people more obvious, i used a two heads, leaning / looking towards each other inside the heart, with one line strip, that looks like they are reaching into each other arms / patting / etc , as to give the message of being a caring companion, also that arm / line abstract can be seen as a smile mouth and two eyes above it, just another perspective.
Hope you like this one, let me know your comments so i can develop on it further.
On a side note, and as a moderator mentioned at your contest public page, it is a known conduct here, the designer who comes up with a unique concept, is the only one allowed to develop on that concept and work on fine tunning it for the CH liking.
I therefore, retain the following as my unique introduced concept at your contest :
1. using a heart shape / with humans / inside a house or scoping the whole house from outside the heart
2. using the wheels to the bottom of the house / heart shape to give the motion aspect
Other designers are welcomed to use any other elements or the boxes for example you mentioned straight in the brief.
Thanks for understanding, and let me know any feedback you get or suggestions you'd like to see specific and i will glady re-work on them for you.
