Like anything, it only bothers me when I compare myself to others. But in my experience people want art for cheap or free...or they'll just steal it. I have to try and not let that get in the way of joy of creating. I didn't care about money when I started making art as a child, after all.
Most art work posted here can be requested as prints, I just hadn't bothered in years. I have an Etsy shop and am on Fine Art America too. The latter I've ignored as well but I think I'm going to try to sell my Instagram shots through it, as that's my main creative output these days. Get ready for link-a-palooza:
