My thoughts:
I would like to have #81 & #81 sort of combined such that all three colors (green, brown and blue) are used, one for each ring. Maybe you can try making the inner ring on #80 brown and the inner ring on #81 blue, and see how that works. Have the word "project" coordinate with the inner ring, which now represents the youth to me. :)
Also, and this may be taking the symbolism too far, we typically start with 8 youth in a group. Wonder if you could make the inner ring work with 8 stones, without it losing its organic feel?
Ok, now for the fire. The actual flame is elegant looking and the little sticks are adorable(!), but they make it feel off-center to me. And, the perspective is head-on, while the ring is - again, in my mind - an above view. Hard to imagine what it would look like, but the closest I could come up with was something in the spirit of one of these (the first two images in the third row stand out to me, perhaps with less white space in the center):

More just trying to give you a sense of a possible direction to go. I knew this was going to be an issue but couldn't come up with any ideas about how to approach it before.
Oh, and for #79, I actually liked it with half the stones brown. I was wanting you to change just the innermost stone to blue with some green splotches to suggest the earth from a great distance, kind of like:

Wonder if that might work in #71 as well?
OK, no more! I just keep having all these creative explosions and can't help myself.
Warm regards,
Jai
PS - The people in the "footprint on the stone" camp have all commented on #72 now. Here is one comment: "Having seen the new ones, I have changed my vote. 72 is quite simple and beautiful. Color is nice as well. "
You're competing against yourself now!
