Crises laments that bigger MOCs get noticed while smaller ones do not. Personally I don't feel this is so. Here, at MicroBricks and to some extent at MinilandBricks I celebrate great smaller MOCs. Tony made a great point in the comments that venue is very important. When I'm online, looking at a 600x450 pixel photo, I'd actually rather look at a smaller MOC - if the MOC is some layout covering multiple baseplates, you just can't see the details. OTOH, if you were at a fan convention or other public showing, I can see why a huge castle or something draws attention away from a much smaller MOC.
