Your skill level, or what ever you think your skill level is, is irrelevant. What you need to figure out is who is your target market.
There are plenty of bad artists that make a pretty good living selling awful paintings at beach fairs and farmers markets.
There are plenty of great artists (for whom art is their entire life, not just a hobby that they picked up) who can’t even make a living and therefore must take on other jobs to pay the bills.
There are plenty of artists, who in their own time were overlooked, but now their work hangs in the most important museums in the world.
Also, art is in the eye of the beholder. Some people think Jackson Pollock was a genius, other people think he ruined perfectly good canvas with drips and splats.
A few of my friends are full time artists. They all have their own websites, but they also network and have agents. You most likely would need an agent to get a show in a gallery.
If you really want to be successful, you need to be extremely prolific, and be good. Not just one or the other.
You should also look into craft fairs, street fairs and farmers markets. They all sell artwork.
You should also research art competitions, big and small. You tend to get more recognition if you manage to get yourself into a juried show. The more the better, and that way you build your portfolio and your reputation.
Another friend, got a windfall when he got a contract for creating the artwork in one of the new hospitals in our city. Not sure how you would go about that, but you most likely would have to have an agent and a body of work. Same thing for hotels.
So the pricing is completely subjective and subject to where and to whom you are selling.
Most of the locally owned (not franchises like Starbucks or Peete’s) have local artists showing and selling their paintings, some for a few hundred dollars a piece. Even my local post office has paintings for sale.
And of course, there are always commissions which can be acquired through your own networking, or with the assistance of an agent.
Good luck with your art work : ) Hope you can post something for us to see!
