Here are a couple that I think are pretty nice.

I like this one. Last spring I did an HVLP paint job using some $7 ace rustoleum paint in a color I picked off the house colors chart! My dad decided it was the perfect color for his bus, so it got it too!

This one isn't very good, but I think mid-project garage shots can be great.

I think a monthly or weekly photo contest would be great! There are some great picture takers and photographers on this site, and some beautiful bikes as well.
