Prompt-
Create a image of the uploaded person with this following details Subject and Attire
The subject is a man with a muscular build, short dark hair, and a trimmed mustache and beard. He appears to be in his 20s or 30s.
He is dressed in athletic wear:
A deep red or burgundy T-shirt with a white logo centered on the chest.
Black athletic shorts.
Grey and black athletic shoes with white soles.
Accessories include a black smartwatch on his left wrist and a couple of white and black wristbands on the same arm.
Pose and Expression
The man is seated on a black workout bench or piece of gym equipment, facing mostly toward the camera with his body angled slightly to the left. He is leaning forward with his elbows resting on his knees and his hands clasped or resting lightly together.
His facial expression is extremely friendly and genuine, featuring a wide, beaming smile that shows his teeth, and his eyes are crinkled with happiness. The expression conveys approachability, confidence, and excitement.
Camera Angle and Composition
The image is a vertical (portrait) shot taken from a straight-on or slightly low camera angle, which helps to showcase his physique and the surrounding environment. He is brightly lit and centered in the frame.
Background and Surroundings
The surroundings are distinctly those of a gym or weight training area:
The background is dark and blurred (bokeh), focusing attention on the subject.
The dark equipment in the background includes weight racks, machines, and benches with industrial metal structures.
The most notable feature of the lighting is the strong red and dark lighting scheme. The subject is illuminated with bright white light from the front, but the deep background and some highlights around his shoulders (especially on the right side) are cast in a dramatic, energetic red glow, which is typical of modern gym aesthetics.
A pair of dumbbells are visible on the floor in the immediate foreground, just beneath his feet.
The overall mood is one of high energy, fitness motivation, and friendly professionalism.
You can tweak this prompt by changing the lighting, expression, or background style to create your own version.
