Thank you for making that point about eye contact not working for everyone. Obviously this is something I'm still thinking through, and you are absolutely right that showing someone with their work or at play would also function well. (There are some pin-up styles that show people at work or play and yet focus on titillation, so, not a hard and fast rule.)

Thanks for that NK Jemisin link!

Like all "rules" I think this one can be broken and is more of a guideline.
