#1 and 2 have the best composition.. Everything else is just chopped up or cut off so it is hard to tell what the view is actually supposed to be.. (I know it's Alcatraz, but I mean why that shot)
I'm not much of a B&W fan in this day and age so won't comment on those..
The last one could be an interesting shot, but way too much noise and lack of distand detail....
I must clarify, I, myself, didn't realize that most of these were taken with my $100 p&s. I was just playing around in Picasa, and after it imported a whole computers worth, I just went and started fudging around with the ones I liked, not trying to mislead anyone, I fooled myself.
