픽셀 아트 레드 드래곤과 고성

A retro fantasy pixel art scene in a square composition, showing [a huge red dragon] perched protectively on the tallest central tower of [an ancient stone castle]. The dragon features a long curled tail wrapped around the tower, large spread batlike wings, a lowered horned head facing left, a glowing fiery red-orange body with dark maroon shading, and crisp black pixel outlines. The castle is a weathered medieval fortress with crenellated walls and narrow windows, perched atop a steep rocky hill. Rolling green and brown mountains wrapped in pale fog and low clouds form a layered background. The sky shows a dusky twilight gradient of [lavender and muted purple], faint pixel stars, and distant birds silhouetted against the horizon. Classic 16-bit sprite art aesthetic, visible pixel grid, limited color palette, clean silhouettes, side view landscape framing.
