Thank you all again for the comments.
Colin:
Unfortunately, I have never tried to make a mold before and I certainly didn't feel that my work would be good enough to be sold commercially. This being my first original piece, I actually used painting as a way of determining if subtle changes needed to be done. Bottom line is "Erwin" here will stay as a one-of-a-kind experiment for now. In the future, if something I sculpt that is worthy of reproducing, I will be hounding you guys for advice.
Regards
Dave
