Note that the other shoulder was not as prominent, but still needed a little touch-up. I often use the macro setting on my Nikon D2H's 28-105 lens as a back-check to discover any imperfections. I always model with an Optivisor, but even then I can't see every single flaw. I noticed that when I did closeup photography of my finished kits I was always discovering gotchas, so I now use it to find 'em before I paint 'em!
