sorry jonb, but i prefer the original over the crop.
the car is definitely the subject matter, there is no doubting that, but cutting the background matter in this case the windmills in half makes the windmill stand out more as you look at them and go "what the hell is that big white stick" since you can't see the spinning bit.
The original composition was fine and interesting, it did run close enough to the rule of 3rds,
and the horizon rule. pfft thats meant to be broken!
heres my quick edit to make it stronger.
i'll be first to admit i went a bit ott on the sky.
