If people stood back from their layouts a little more and squinted at what they had created, thus taking in the 'feel' rather than concentrating on fine detail, there would be some more inspiring work out there. I think of layouts as a bit of theatre or a moving painting. Composition should be such that the viewer's eye is contained within the scene, if the eye wanders 'off set', then the builder has failed.
Capturing atmosphere has nothing to do with the correct number spokes or whether a rivet is 0.5mm too low (or maybe high - heaven forbid!). Composition, colour (a major problem) and overall design are so frequently missed by a country mile, I suppose it's down to that fact that many modellers, whilst mechanically highly skilled, lack the ability to 'see'.
We're all different, the hobby would be very dull if we were all striving for the same thing. We need the engineers, the impressionists and I suppose the dreamers too?
