Create an illustration featuring a girl seen from the back as she looks out of a window. The style should match the reference image provided, capturing the same level of detail, color palette, and atmospheric lighting. The scene should be set in a dimly lit room with a somber, eerie ambiance appropriate for a horror story. In the background through the window, include distant mountains shrouded in mist to enhance the sense of foreboding. The girl's posture should convey a sense of unease or anticipation, contributing to the overall mood of suspense. Ensure the colors and shadows are consistent with the reference image, emphasizing the contrast between the dim interior and the slightly illuminated outside view.
