thanks for your excellent comment. I reduced the pattern from 120 to 100 pixels and reduced the opacity of the pattern slightly.

AT Hoboken Terminal, (NJ) which supplies a 9 minute ride into the city which travels UNDER the Hudson river. (The Path) You pop out right where the World Trade Center used to be and you travel through all the broken connections created by the terrible attacks of 9/11. (Almost all are repaired now, or at least given a shiny face of recovery.)
I took pictures of that area. (Hoboken and the linking areas, something a Midwesterner is very new at.) The face on the man is EXACTLY what I was feeling when I went on these routes the first time. Once the over all overwhelming feeling is done though, the trip is no big deal.
If you ever get the chance to ride on a subway, going UNDER the Hudson river, and you see the Train Car in front of you through the connection door, and you watch it dance and jump and wiggle, you can understand the face of the Man I merged with these images to create the feeling I had. I was confused/excited/overwhelmed by the effect and tried to reflect it in the image.
I can now ride the subway with no tension, and no fear, but the first time is so new and different, I wanted to reflect that feeling. (Also my eyesight isn't so good and when pictures get too little they just confuse the hell out of me, (Like the ones in the mosaic from the tutorial.)
