Jon, Nice clouds and soft lighting in the sky I dont really think that the fill flash adds much for this particular challenge. While I realize this was not taken for this specific challenge, I would consider using the light from this type of sky and let it light the car for you (as opposed to fill flash). For added interest, perhaps you could also capture a reflection of the sky somewhere on the car and change the perspective from which you are photographing the car (e.g. not head on or at 90 degrees). I also find the prominence of the foreground unnecessary. Im not trying to be abrupt just stating what I think would improve this type of shot. : ) Best regards, Brian
