Linda - Thanks so much for the encouraging feedback! I've no experience with marketing at all, and this will probably be the only thing I put out there, for awhile anyway. We'll see what kind of response it gets!
The idea of displaying the portrait with some 'process' photos is very interesting. I've taken some along the way so that would be feasible - maybe initial underpainting and an intermediate stage together with the finished portrait? Would it be tacky to put something like that on one side of a postcard with a little blurb describing it and perhaps a pricelist on the back? You know - something that people could take with them if they were interested?
Here's where she's at now... I've still got work to do on some of the color & transitions on the arms but am planning to start fleshtones into the face Tuesday... and will finalize all fleshtones (arms and face) together once the face is caught up to the arms.
