Bold digital-painting motivational portrait poster

Create a dramatic digital painting style portrait of a young male, reference image without glasses, looking upward with a strong, determined expression. The artwork should feel bold and textured, with energetic brush strokes and a limited color palette of black, white, red, and yellow. The background is split vertically with abstract red and yellow paint streaks, giving a powerful and intense mood. Focus on ambition and confidence in the subject's gaze, with a clean design that has no text, no slogan, and no logo anywhere in the frame. The composition should feel motivational and poster ready, high detail, 8K resolution, image aspect ratio 4:5.
