These are thumbnail sketches submitted by Leslie.
Leslie I like your idea of using had as a main element. But top of your hand tends to be little more difficult than other gesture of a hand due to a limited formation.
I want to suggest something like this, it does not necessary need to be "reaching out" motion, but something that has more gesture in it.
We need to finish this project by next Friday, so please use the same technique you used for your previous project and limit using any element in the background.
If you have further question, please write as a comment.
