i like this pic of this '87 schwinn letour
it's not perfect. but it's interesting. the background with the setting sun is great. the angle of the bike may not be perfect, but the angle creates a sense of action that mere horizontal lines don't provide. the lighting in the bike itself could be better as the red paint doesn't pop like it should.
simply put, a lot of thought should go into a good photograph. you've already spent dozens of hours rebuilding your bike. you should spend thirty minutes or more capturing it with a camera. but it's hard work, and can feel like a burden after you've finished your project.
