CR7 Portugal Starburst Poster

Create a dramatic square sports poster featuring {argument name="football player" default="Cristiano Ronaldo"} as an iconic Portugal national team legend. The composition contains exactly two depictions of the same player: one large heroic bust portrait in the upper center, cropped at the chest, looking slightly upward with a serious determined expression; and one full-body action figure in the lower center sprinting forward toward the viewer while dribbling exactly one blurred soccer ball near the bottom edge. The player has short black hair, sharp rugged facial structure, realistic skin texture, sweat highlights, and an athletic muscular build. Dress him in a Portugal-style red home jersey, green shorts, red socks, and football boots, with the number {argument name="jersey number" default="7"} clearly visible on the chest and on the shorts, plus a captain armband on one arm. Use an explosive radial starburst background that starts behind the running player’s upper body and expands outward to all edges, made of hundreds of multicolored light trails in red, magenta, orange, blue, green, white, and purple, like hyperspace motion streaks mixed with stadium sparks. The overall look is high-contrast, cinematic, glossy, gritty, and energetic, with sharp poster lighting, strong rim light, motion blur on the ball and limbs, and a dark textured pitch under the runner. Include exactly three small typography areas: large bold glitch-style white text on the upper left reading {argument name="main title" default="CR7"}; a thin spaced subtitle line split across the upper middle reading {argument name="upper subtitle" default="ICON PORTUGAL"}; and small spaced text near the lower left reading {argument name="lower caption" default="LEGEND IN MOTION"}. Keep the text minimal and integrated into the poster with thin horizontal guide lines. No extra players, no crowd, no logos beyond subtle kit-style details, no watermark, no frame border.
