What's old is new again

I've been trying to come up with a frog design for quite some time now, with no success. Then a few days ago I came across a necklace that I did waaaaaaay back in the early nineties that had a frog and a couple of snakes. I was working in wax and casting it myself back in those days. I liked the frog and one of the snakes so much that I decided to make them both. The larger piece on the left in both photos is the original casting. Silver cost around $3 an ounce then, it's currently $22 or so! The green dots are concrete.
