Art is anything that you create with a passion. No matter if your lines are not straight, if your circles look like eclipses or your portraits of human being look like an alien who just landed on the earth. As long as you see beauty in it, others find it interesting/absolute nonsense and/or as long as its been talked about, trust me you have created an art. Art needs no justification, let them judge if they want to.
My suggestion is let down your guard and inhibitions and float free on your canvas in the colors of your choice.
