Logo - Illustration - MobiPack

For helping a friend of mine that needed a logo for her project, I thought of handicap and how to represent it.
The wheel was the best idea because it's already the symbol of handicap like on parkings. I did a version with all the circle and half of it. We can imagine there's a human shape in the middle, and my friend loved it.
The project consist at helping people with disabilities to find some places where there's no problems for them.
I did an other try right here.

What do you think of it ? I still think it miss something, but I don't know what...
