#67, #65, #64 - thank you for these submissions. We think that these are a bit too organic for the type of organization we are creating.
#66 - The simple addition of the sphere speaks to me that this is a person protecting something. Not sure if that's the right message to send, but recoloring the larger sphere green may signify the protection of money (spend). Its a longshot, but might be worth giving a try. Thanks!
