A detailed retro fantasy pixel art scene of a massive medieval stone castle perched on a steep rocky hill, viewed from a slight low angle, with a winding dirt path leading up to the gate. The castle has many cylindrical towers and connecting walls, exactly 9 visible towers with red-orange conical roofs, several small red flags fluttering from the tallest spires, and weathered gray stone masonry. A huge red dragon is coiled around the tallest central tower, with its long body wrapped around the stone, claws gripping the battlements, horned head leaning forward near the top, and one large batlike wing spread open on the right side. Surround the hill with dense dark-green pine trees and rocky outcrops, with distant blue mountains on the horizon. Place the castle against a bright daytime sky in saturated blue with large fluffy white cumulus clouds. Render in classic 16-bit inspired pixel art with crisp sprite-like shapes, visible pixel texture, rich contrast, adventurous fantasy game cover composition, centered subject, and a square frame.
