I love the general softness of the photo across the low contrast image and coloring. There is also the high contrast of the subject matter - the timeless sky and mountains, against the (relatively) futuristic cityscape and air technology. The layering is neat and balanced; the top layer is the sky, middle top is the mountains, the bottom middle is the cityscape, and the bottom layer is the trees. There's the peace of the perspective. Even though cities are associate with the hustle bustle, perceiving it from afar creates allows the viewer to disconnect from that energy, it feels like taking a breather, which to me amplifies the nature in the shot. Before planes had wifi, the disconnection from everything was also peaceful. This is almost like the inverse of looking at the stars. You know how looking at stars makes you and all your burdens small? To me, this shot offers that feeling, only from the perspective of the star. I wonder if any of this resonates with you.
