I get it, your logo is indeed beautiful, I may have even designed it myself. However, design is a balancing act where elements need a certain amount of asymmetrical balance.
Throw that balance out of whack, and it’s a quick way to bring to mind the feeling of those throw away ads in the Sunday paper. The more we nudge the logo ever larger, the more slippery the design slope so to speak.
It’s not some kind of unwritten rule in graphic design that logos adhere to a specific size. But the client-designer relationship is one of trust. No matter how tempting it may be to improve on a good design but punching up the size of the logo, it’s definitely best to err on the side of modest elegance as opposed to that used car ad look from the Sunday paper.
