Autumn leaf necklace

I had created these enamelled leaves a long time back as part of an enamelled panel, but after a long time of the panel just sitting in my studio, I got tired of looking at it and decided to 'up-cycle' it and use the leaves in my jewellery. This is the first one in the series although I do not think I can use the rest considering size constraints.
         I gave this one a neck piece made of brass and am working on a metal chain to complete the piece. What do you think does it look better as a necklace or where it originally was?
