Illustrate an artistic self-portrait of an individual wearing a mix of clashing colors and patterns, with bold accessories like oversized glasses and a quirky hat. Artistic style should be a blend of expressionism and modern art, using digital painting as the medium. Use a standard lens with an aperture of f/4 to balance the depth of field, focusing on the face and accessories. Lighting should be studio lighting with dramatic shadows to highlight the textures and colors. The background features a chaotic mix of brushstrokes and vibrant colors that enhance the sense of individuality. Focus points include the expressive face and the details of the accessories. Apply a glitch art effect to create a sense of digital chaos and modernity. Use color grading to make the colors pop, and add a vignette effect to draw attention to the subject.
