Excellent
That is an ass-load of detail - no wonder it took so long! It's got a deceptively good composition - nothing seems to stand out but there's a good deal of variation in the actual machinery, and I like how the green just subtly takes it away from full monochrome. How the hell did you scan something of that size? Or did you do somethin' else to get a digital version?
Point is, man, great piece. Definitely worth the front page.
