Hi Diane,
So sorry you have been having such a hard time - I went through this myself a couple of months ago and almost gave up. This wonderful bunch of people got me through and now my sales are doing well again - hit and miss, but generally I am doing ok.
What works for me is to do various subjects - I get bored with the same one anyway. I have a few fantastic repeat buyers who just buy one particular subject, so when I feel down about lack of sales I paint something that I am sure will sell, they usually don`t take me very long and I get to see the green numbers on my listings again 🙂
It can take time to get a following, as everyone is saying, just stick with it and one day you will wake up and switch on your computer to a bidding war and you will feel fantastic!
Just a point, as Chris said, would you sell to the UK or worldwide even? There is the most beautiful seascape in you shop that I would love to buy, but I am in the UK and I see you only sell to the US. I have to say that most of my buyers ARE from the US and Canada, but I still have some great buyers from the UK - it seems the word is spreading over here quite quickly.
Also, good advice about "resting" some of your paintings for a few weeks to keep your shop fresh. I have found that re-listing after a few weeks often gets a sale.
Chin up Diane and DON`T give up, your work is beautiful and will make lots of people happy.
