Here are my entries. I tried to keep the figure somewhat abstract, but still show the concept of dependence/warmth. I think that, by putting a stronger focus on caring for the child, you can make a stronger connection with volunteers/contributors. It only shows care for a child - rather than all the things that the trust will create for the child. I personally don't think it's necessary to show the extra things - that's what pamphlets/informational meetings are for. The name alone says it all. I believe that the key point you should focus on is to bring help to the trust by showing emotion and the intent to help a child.
just my thoughts - it's a great thing that you guys are doing!
