Using this selfie of me, create a professional headshot. Keep my face, facial features, skin tone, hairstyle and expression exactly as they are; do not slim, smooth or change my features. Change the clothing to [outfit, e.g. a navy blazer over a white t-shirt], background to a [backdrop, e.g. soft grey studio backdrop], soft key light from the front-left with gentle fill, head-and-shoulders crop, eye level, 4:5.
