In the profile shot of the finished chrome frame there is a tangent from the bottom of the head tube to the tire in the background. It throws off the composition of the photo. Could you re-shoot that one?
Seriously, that was so detailed and informative you should get some kind of SS/FG prize. I was surprised the photo was a little bit off because of your attention to detail.
Also could you put a neutral background behind the frame, off white maybe.
