Thank you for your support. Keep a few things in mind. I'm new to this field. I have no idea what a painting might be worth. I don't know of any place to sell artwork, not even in my own country. And as a last resort, I live in Cuba, where connecting with the world is a complicated issue. I have a lot to learn. Many barriers to overcome. I am very grateful to @wakeupkitty; without her motivation and help, I would never have started painting.
But keep in mind that art changes lives. It produces effects and feelings that cannot be replaced by anything else. That is art, what flows from the soul when you dare to dream and create.
