I ask because certain bentos stand out (make me say, "Wow!") and others don't, and I'm not sure what the difference is, since they don't seem that different upon closer inspection.
I've noticed that well-lit photos helps a lot, and leaving no gaps seems to add to the perceived quality (at least, to me). But I'm not sure what else pushes a "good bento" across the line to make it a "great bento." I know it's not the difference between charaben/kyaraben and regular bentos, because non-cute ones can still wow people. And I don't think it's the complexity of the bento either, since some very simple bentos still look a lot better than complicated ones.
What's the secret?
