I think some of the modern designs could use a bit of attention paid to their colour scheme to try and visually conceal some of their bulk.
Sort of like "Does my F3A plane look fat in this colour scheme?" An airframe with clean lines could be painted with a hessian sack and still look good, a bloated goldfish not so much.

I've been leaning towards springing for a Proteus bipe. In some colour schemes it looks like a lean, mean piece of kit but in others it looks like an ugly dump truck.
