New interactive design

I am wanting to build the visual component of an interactive component on our website that teaches users how to sanitize their hands. If you go to this link, [login to view URL] Check out the 3rd interaction. You will need to go through the first 2 and you will see the current way we do it. I am wanting to improve this interaction and make it better. What I am wanting visually is germs that you can see on the hands and that will be killed when you put the hand sanitizer on and start rubbing them together. Below is a link to a sample hand washing interaction we had built with the bugs on it. We are still not happy with this, but this is our start and can give you an idea of what we are looking for. I don’t mind if it is in 2d if it looks good. [login to view URL]
