First thing...detail, absoultly perfect, every single line was perfectly taken, no smudges from camera movement, nothing, just hard, sharp lines...this is what professionalism is all about, excellent job Phil.
It's a nice idea, but the colors of the photo are a little weak, washed-out. This could be caused by the source of light you used. Sunlight in the late afternoon has a nicer (warm)tone. You can also try to change some things in PS. But I think, the subject is great!
