The horse is great. If you want to your work you should find a gallery that will represent you. Get a show. Even if you get representation at a coffee shop or diner people will be seeing it every day. Start a website or a blog. Get people to look at your work. Eventually they will sell if you get them seen by the right people. If you have money pay an art consultant. A consultant will know the right people and may be able to connect you with people who sell the kind of art that you create.
