Pretty standard cars in a parking lot shots. They are ok, don't get me wrong, but they don't have any wow factor at all.
Might just be me, but I'd love to see some really close up shots bringing out the details in the cars...the headlights, the smile, the mags... maybe with a wide lens.
Or taking a journalistic approach and getting a shot of the owner of each car with them, telling some sort of story.
Yeah, I've tried to remove that spot with a spot removing tool. The lens is a 35-70mm f/3.5-4.5 from 1987. It hasn't gone away for me, so I don't think it is on the front of the lens. Trying to figure that out right now.
