See, now this proves everyone's taste is different, along with what they call a cliche. I like that Buick, and it's something I could see printed and hanging, and people paying for. The other, just looks like a snapshot to me, nothing I would more than glance at, let alone want to pay for, print or hang (not an insult).
I have not had the opportunity to take any shots of such rusty cars or machinery, and would gladly do so at my first. I would not at all hesitate and say 'oh gee, I shouldn't take this, I know it's been done before'. It's just completely irrelavent to me. If I like it, I'll take it. If it looks good, I'll print it. If someday I try to sell something, someone else may buy it.
Someone else may have taken a similar shot, but you can't print someone else's at will, let alone sell it I want my own!!
