Good direction, simple yet containing hints for unification, collaboration. Can you think of some additional hints for community, people, communication?
#20 is also a good idea. Can you try to elaborate on it also, please? Some other twists, maybe you can try to make the inner edges round as well, or just whatever comes to your mind.
I definitely like your designs more, I'm just trying to get more ideas and variants to choose from at the end. Thanks.
