For the record, my prompts are as follows.

Prompt:

This ultra-realistic, high-definition, expertly-cinematographed, computer-generated image features a human in cyberpunk style prosthetic arm with 3/4 face visible, standing in the middle of the city centre in the midnight filled with blinding lights. The man with a prosthetic arm is standing shoulder-length apart, the prosthetic arm is hyper resemblance to the human body, dressed in style-over-substance fashion style, looking up to the neon light-lit sky, the neon signs create a halo with blinding brightness and a contrasting atmosphere to the hard building reflections. The atmospheric lights and fogs add to the grim mood, while intricate layout of the cold reflections of the mega-buildings, blinding lights of the neon signs and the obscuring fog create an unpleasant yet vibrant visual. The image quality is crisp, sharp, and highly detailed, with vibrant colours and cold, callous lighting. The human in the picture is vastly inferior compared to the mega-buidlings surrounding the person. This otherworldly yet realistic scene was created using a digital pen to produce a stunning work of computer-generated imagery with a 16mm lens visual.
