<https://s.mj.run/dK-7mpJQwbM> Generate an image with realistic mountains in the background of this photo of a thermos. The mountains should appear natural and blend seamlessly with the scene. Ensure that the lighting matches the original photo of the thermos. Pay attention to details such as texture and shading to avoid a cartoonish appearance. The perspective and proportions of the mountains should be accurate to create a sense of depth. Incorporate the brand "Pampero" subtly into the scene, perhaps on a small tag or engraved on the thermos itself. Avoid overwhelming the image with the mountains but make sure they provide an interesting and believable background.
