Gold leaf photography

I've recently aquired a canvas light-box to hopefully make me use my camera more over the winter months when it's more difficult to get outdoors for photography, especially during the week. As the autumn leaves have been falling, I thought it would be an interesting experiment to take some backlit shots of some leaves using the macro lens, and these are the results:
