Wow! what a number of responses! sorry for the sarcasm :) oh and further it was Valentine's Day when you posted this! And not one person answered... what a bunch!
I was asking myself the same question.
I do have one suggestion... update regularly because the new stuff is always seen first and depending on where you live adjust price (like me, where I live in Gatineau Quebec Canada) not that many people have money to buy art or want to spend money on art, BUT if you live in Hilton Head, SC...like a friend of mine, he sells more paintings in a day that I do in a month and he sells them for at least $5000.00 a piece (lots o money in HH!)...
I guess that's all I know... sorry I couldn't be more informative.
