I like them, For the second image; I would have put one of the other triangle objects in focus as opposed to just the snippet of one in focus, but to each his own.
I love the second image. I agree with averageJoe, I would have maybe focused on the third triangle (are those tire spikes?). Also, keep in mind that I'm a very new to photography, just my $0.02
I like them both. Wouldnt change the contrast personally, but I prefer more contrast. I am curious what difference having the second shot focused on the third spike would add....but I like it as is, might be better on the 3rd..don't know.
