I'll be the bad guy today.
I think that the location, the overcast, and the wet, gravel covered, puddle laden "roads" did nothing for your car, and actually hurt.
I think your car will look 100% better ( the car itself clearly is very nice) if you get it on some blacktop w/ the sun shining either very early or very late in the day. I mean it's silver and black, it needs something other than grey overcast to contrast against.
I understand that you are probably wanting to get a more "raw" feel to the pics, but there are just too many other distractions that diminish the cars' positive attributes.
I mean I'm no expert, I just learned some of this junk myself since I started taking pics of mine.
Not dogging the car,....just the location.
Now i'm going to confession for badmouthing somebody.
