天空背景和阿尔法遮罩的广告牌

green billboard stands against a vibrant blue sky with white clouds drifting by in a time-lapse sequence. The large display creates a striking contrast, perfect for emphasizing the empty space and potential messaging. The billboard is isolated with an alpha matte, making it ideal for seamlessly blending with different visual elements or backgrounds while the clouds continue to move.
