I don’t think so. They live on the side of a canyon. The fog comes from the river at the bottom. They are looking at a mountainside facing the mouth of the canyon. I live in the Alps, you have such views on the small mountains leading to the higher ranges (minus the canyon wall on the right, this one will be hard to find here).
Oh I don’t want to be confrontational at all! I am just trying to understand what I am missing, as usually I am nitpicky with perspective too but could not spot the mistake there! Please dont see that as a very serious or angry argument!
I am not assuming a ship, but a cave, so from a point of view of low altitude. I imagine the camera being horizontal, at the level of the tallest person’s head. I see 3 layers on the background: the canyon wall on the right, fairly close, the small ridge with what looks like a nice ski slope on it and a big mountain in the background. Granted, that one is huge, you may need a 1500 or 2000m differential between the window and the background mountain top but I think I could find such spots on Google Earth in the Alps or the Himalayas.
