A young man sits casually on the edge of a rooftop/concrete wall structure

Photorealistic 4:5 vertical image. Slight low-angle camera positioned a little from the side, not directly facing the man's chest. A young man sits casually on the edge of a rooftop/concrete wall structure, with his feet completely out of frame. He wears all-black clothing. One hand rests naturally on his knee, while the other hand is raised near his mouth/chin. His body is slightly turned away from the camera, creating a natural side-angle perspective but his face is visible in camera. Above him is a vast blue sky with realistic soft clouds. In the middle-upper area of the sky, comfortably away from all image borders and with plenty of clear space between the text and the man's head, the words "Believe in YOURSELF" are formed naturally from clouds. "Believe in" is elegant flowing cursive with a large dramatic B, while "YOURSELF" is directly underneath in bold uppercase letters. The typography looks physically formed from soft white clouds, realistic, atmospheric, and seamlessly blended into the sky. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
