Dark atmospheric concept art of sinister, devious woodland monsters. They have dark bodies covered in branches and twigs, with gray goblin-like faces featuring black, malevolent eyes. The creatures, small and crawling on all fours like Gollum, are spotted from a distance of 100 feet, emerging from a cave in a dense pine forest. Moonlight from behind them casts eerie shadows, making their details barely discernible and heightening the sense of dread. The scene is set at night, capturing the creatures as distant, creeping figures, adding an unsettling and ominous atmosphere. In the style of Zdzisław Beksiński, with a focus on creating a lurking sense of evil.
