I just had another look at your art and it reminded me of something that i think is awesome. Maybe you will too...

It's called "Freedom Girl" and it is a 1 ounce silver coin. Have a look if you can (just google her). I would send a pic if i knew how to do it from my iPhone...
anyway, she is a favourite among the silver enthusiasts group and she is gorgeous. Enjoy!
