The painting looks really good! Your understanding of the human ear and blood physics really makes it work, and the colors are great for the subject matter. Really makes a bold statement.
Keep up with the good work - with four pieces as good as this one, you’ll be able to be scouted by someone and your work will show up on the art portal. With that added publicity, you might be able to start making money off your art, and save up to move away from your parents one day. That’s just one potential way of getting out of that situation, I’m not sure what the details of your life are, but if your parents aren’t treating you right, by all means start making a solid plan to get away. I wish you the best of luck, and know that you are not alone. If you need a support group, there’s many places around the internet where you can find others who are dealing with much the same thing, as well as other people who want to help in general.
