gateway to another world SN3318

A large, dark, arched gateway stands between two towering structures, opening onto a tranquil scene. A sandy beach stretches along a shore, meeting a calm body of water with a green hue. The water reflects the light source from beyond the arch, creating a shimmering effect. The distant landscape features mountains or hills shrouded in a hazy atmosphere. The structures flanking the archway have textures reminiscent of both natural rock formations and artificial constructions, possibly suggesting ruins or megastructures. Red lights or energy signatures are visible on the right-hand structure. The overall mood is serene yet mysterious, with a color palette emphasizing greens, yellows, and dark, shadowy tones.
