Playground Setting Atmosphere & The Terminator 2

Looking for a mysterious, mystical, uncanny low lit, foggy atmosphere to keep the audience on their toes and allow them to embrace a scared, curious, unnatural emotion. This helped me gain a perspective of where the playground assets would be in comparison to the scenery. Reflect the mood we are aiming to achieve. 

The first image was the playground scene in The Terminator 2. The whole idea of the chariot of horses on fire and it being the apocalypse had nothing to do with our storyboard or game but the effects are strong and perhaps directing the attention away from the creepy mysterious feel.

Again i''m referring to silhouettes as it really exaggerates and enhances the mood. Between the yellow and white light, i feel the white is more realistic as the yellow reminds me of possibly a UFO or alien being involved. The red emphasizes a big ball of fire about to erupt and the fog above is the closest match to what i am looking for.
