Edit 4 of the 1st picture looks pretty cool. I'd crop out the rusted dumpster so the car sits in the bottom corner of the photo. Something about the dumpster doesn't look right and shots are a little more dynamic when the subject isnt' dead center.
In the others for pic 1, there is a little bit too much contrast going on. Your losing alot of details in the car...which is your subject.
Something I'd highly recommend would be to clone out the wires dangling around all over the place. They're kind of distracting and take away from what the photo could be (not your fault...just the scenery). If you cloned them out, the car would be able to show itself off a little bit more.
I like that dumpster actually, does take away from the focus, but the centering lets you know what the focus really is. I think the dumpster adds to that dark gritty feel I was aiming for. Yea, I agree with the off center bit, Thats why photo 2 is like that, I mix it up.
The edit #2 and #3 on pic 1 are a bit dark, but that photo its self came out dark. Mainly that corner under the A/C unit. I want to play with adding external lighting, but its difficult when your mobile. IDk, I'll get something one day. Thats the only way I think I can really get some shine in those shadows on such a dark car. I cant photoshop it, its gets to pixelated and just poor looking.
Wires is a good idea, just clean up the hanging ones, lol, that will be fun to try.
Thanks for the detailed response.
