I like them very much ... back in the day, if you wanted the amount of grain in one, you had to know what you wanted and develop the film in a paper developer. HOw you do it isnt as important as know what you want to do with it. I like them all.
Number two is very interesting, I have to wonder what the second shot would look like if there was no white space to the right of the man's head. If his head went all the way to the edge of the frame. Just a thought no big deal they are very good shots regardless.
