Untitled AI art by @Wildemark

A book cover artwork. A scary tunnel entrance is seen. In the tunnel runs an electric cable with weak orange bulbs fading away in the dark distance of the tunnel. Four older teenage boys are standing in front of the entrance, with their backs to camera. They are staring at the entrance, trying to get courage to enter. The sky is dark and gloomy, and there is a creepy mysterious feeling about the image. No text. The image should be photo-realistic.
