Bold digital painting sports poster of a determined footballer

Create a dramatic, digital painting-style portrait of a male footballer looking upwards with a determined expression. The style should be bold and textured, using dynamic brushstrokes and a limited color palette mainly black, white, red, and yellow. The background should be split vertically with abstract red and yellow paint streaks. On the red side, include the bold motivational text ‘I’VE JUST BEGUN’ in large white, hand-painted font. Capture the intensity and ambition in the player’s gaze. The composition should feel motivational and powerful, ideal for a sports poster. 8k Resolution, Image Aspect Ratio 4:5."
