Your new concept #250 is very nice! i like the one standout person in the O icon. could you tweak the font color to a bluish grey color? somewhere in between the blue and the grey options you have.
concept #293 is really strong. i like that it looks like individuals around a conference table. i think the icon needs to be a bit smaller and maybe add a circle in the middle so it can be recognized as an O.
Would you modify your concept #261 to be like entry #272 where the icon goes around the text? i really like the look of that design but i think your icon is much stronger. thank you!
I like #308. i think there should be 4 on top and 4 on bottom. you could have one of the top middle icons as blue ... this will give it more balance. i also like that in the smaller version the body lines are straighter...we're really close i think!
could you center the icon around the second O in #310? it doesn't quite look centered on the current design so it's off balance. you could also try expanding the icon and center it on the text.
