Sorry for the delayed response. And thanks you very much for your feedback. I really appreciate it. Here are the version as you requested (#50, #51, #52, #53, #54 & #55). Please let me know if you have any request to revise the design.
For #5 could you make it have 3 circles instead of 4, symbolizing a couple and 1 mediator? Also, make solutions that make sense in the blue of the symbol?
