I ranked #21 lower than
#20, and I want to give you an explanation.
I did actually like the idea of putting a symbol within one of the four "talk boxes". Especially, I think it might be a good idea for the sub logos. However, there are two things I didnĀ“t like about the particular "shouting" icon in entry #21. Graphically, I think some of the lines are too thin. And more importantly, "Min Aksjon" is about raising money for charitable events - using your network of friends and family. Shouting is not the best symbol of this. It is not agitation. So something about pulling together, community, lifting together, inviting etc would be better symbols.
But I like your base symbol in
#20, so keep improving it! :-)
