Give me a description of yourself, what colors you're drawn to when looking at the sky, or your favorite time of day/type of weather. Is it cloudy? Is it clear? Is it like cotton candy or painted brush strokes across the sky. Colors have been linked to energy, and which one resonates with you has a lot to say. Any descriptors of color that you have or pictures that you like will all come together into what your aura is. This is not limited to our perception of reality and the sky could be green if that's what you feel.
Option of digital painting, or a physical painting that I'll take a photo of, or use of a photo from my collection that fits you.
