Regarding the lighting in my render, I have made sure to capture the exact lighting angle that is considered canon in the game. Unlike in the trailer, where Valve had made several changes that don't align with the actual game, I have carefully adjusted the lighting to fit a more realistic and accurate portrayal of the game world.

One such example is the skyscrapers that appeared behind the sign in the original trailer. In reality, these buildings stand on the water section of the map and were only included in the trailer to create a visually appealing shot. However, in my render, I have replaced these buildings with more canon-like structures, which provide a much more detailed and immersive look.

At the end my aim with this render was to not only showcase the stunning visuals of Left 4 Dead 2 but also to pay tribute to the game's rich and detailed world by accurately capturing its essence and atmosphere.
