Too much empty space ... this empty space creates excessive contrast which prevents your subject from being more dramatically lit and colored. I think this is an attempt to fit the rule of thirds in where it doesn't suit you.
Nice photo. I'd love to see it with slight desaturation, not completely b&w but just with less colour to it. Nice composition, with the space on the right giving the impression of the time stopped for this vehicle, and the remoteness of evrything else. 8.
Nice perspective. Maybe take later in the day and it wouldn't be so overexposed. Or crop out some of the grass on the right. I still like this photo though. 7
