I found the shells at a local park and knew immediately that I needed to use them in a carving. I had this guy started and made some adjustments to get them to fit. I have more shells.
(I hope that wasn't offensive; if so, I'm sorry, it wasn't my intention. :S I was referencing only this piece and another small one that seemed to have a happy smile. I hope my comment wasn't disrespectful; it was in no way meant to be.) You are a very talented artist and, going through your gallery, I find your pieces to be very interesting.
