Contest holder was a small full-inclusion art studio that runs extra-curricular art classes and summer camps after school. Their students are ages 3-13, with and without special needs.
I choose to use hands because the art is made/colored/constructed/created with hands and a photo on clients blog inspired me.
The hands are making a circle which could mean all of them (with or without special needs) are a part of this group even if they are all different (presented with different colors) they are united.
