great subject and shot, i really like it - surprised there aren't more junker cars in this challenge. your DOF choice seems like you may have found the windshield the most interesting, and i think i agree. i'm curious if you got any interesting angles/shots of the windshield on its own - they could make for some great images!
Good shot, though ti's a shame about the jaffies around the screen frame. It's a neat compsition too, and I think you do very well not to fall into the common trap of trying t show the whole car.
Is that a Mustang? Looks like you have some jaggies along the A-pillar and windshield trim. Is that caused by cropping too tight? I might have tried changing the gray wall to a different color or shade.
