Sorry it has taken us so long to give you feedback!!! Hopefully you will still have some time to do some back-and-forth on the concepts here before the contest is over.
These are all very cool approaches to the concept, and they are well executed. Some of them, though, are almost too abstract. Maybe a slight improvement to #29 and #30, for example, might be to make the people look a LITTLE more like people. Although I wouldn't overdo it, these logos look like some sort of royal emblem if a customer can't discern at all that they are human figures. Same for #26 - after seeing this for the first time a couple days ago, I am only now figuring out that they are humans holding hands.
While I don't dislike the color scheme in your submissions altogether, most are a bit too subtle/sleepy. You could use slightly different shades to liven/bolden the logos up a bit, or you it would be awesome if you could play around with altering it altogether.
#28 is a cool idea, but I can't help but see the ring as some kind of halo.
Thanks a lot, and we hope you are able to submit a couple more ideas.
