Shannon,
I LOVE this concept!
I don't think it's automatically seen that the finger is missing. I may not have got that if I didn't know that's what you were going for. I think the lines and the text in place of the finger deter from the concept of missing finger. If you want people to not get that idea right away then great, but if you do want them to see a missing finger, you may need to remove some elements (either the lines or the text) away from that section so that there's clearly a missing finger.
Great colors and design though!
