YouTube Thumbnail - GPT 2 Day 500 Gaming Thumbnail

Create a bold YouTube-style gaming thumbnail collage on a dark navy patterned background, using two stacked rounded-rectangle image panels. The top panel shows a high-angle 3D game-like scene inside a circular enclosure of tall bright blue sharpened wooden palisade spikes tied with tan rope, with vivid green grass, a small crop field with rows of sprouting orange plants on the right, and warm firelight near the upper right; in the center stand two real-looking people viewed from above, a man in a light gray T-shirt on the left and a woman in a pale pink T-shirt on the right, both looking upward, with intentionally blurred/featureless faces, and large bold white 3D sans-serif text across the bottom reading {argument name="main title text" default="GPT 2"}. The bottom panel is a wider rounded thumbnail frame split visually between a bright grassy game area on the left and the same blue palisade enclosure on the right; include exactly 2 large text elements at the upper left, {argument name="day label" default="DAY"} in red block letters with black shadow and {argument name="number label" default="500"} in white block letters with black shadow. In the bottom panel, place exactly 1 cartoon deer creature on the left, brown with exaggerated huge white eyes, antlers, open smiling mouth, raised arm, and a red arrow pointing down toward it. On the right of the bottom panel, show the same two real-looking people from above, the woman wearing a bright hot pink shirt and white shoes, the man wearing a bright yellow shirt and dark shoes, both with blurred/featureless faces, standing inside the blue spike fence on bluish ground. Use saturated colors, strong contrast, glossy 3D game-rendered environment, photorealistic people composited into the scene, dramatic thumbnail lighting, thick shadows, clean sharp details, and a viral gaming challenge thumbnail composition. The image contains exactly 2 panels: top panel with the title text and two people, bottom panel with the day counter, red arrow, one deer creature, and two people.
