Creative Text Mask Portrait Design

A highly realistic and dramatic studio portrait featuring {argument name="subject" default="a man who closely resembles Sam Altman, with short brown curly hair, blue eyes, fine eyebrows, and delicate skin texture"}, wearing a dark crewneck sweater. The composition is vertically divided along the centerline. The left half shows a standard photographic portrait against a dark background. The right half is a solid color {argument name="background color" default="dark blue"} background, accompanied by large bold sans-serif text as a clipping mask. The text content is "{argument name="overlay text" default="WE WANT GPT 5.5 ASAP"}", stacked vertically in five lines. The letters act like transparent windows, revealing the man's right side of his face and torso, perfectly aligned with the left side, and presented a complete portrait through typography.
