I like this a lot, and much of his other work; this is beautifully exposed/lit, perfectly composed in my view, and communicates the isolation of the environment really well. Besides which it reminds me of Hopper and that's rarely a bad thing. Interesting decision to exclude part of the vehicle and the tip of the canopy.
To me the photograph owes much to the extent of sky and foreground, which adds to its sparse nature. A rectangular approach would not have offered this and the ability to exclude part of the vehicle /canopy. Square is important to this photograph I think.
