I think this one would be a good place to start....
What plane is that?? A 50% CAP?? What engine goes in that beast??
I voted 40-50 beacuse IMO that's the span range that most profiles look "proportional". When the size goes up, for me, the level of ugliness and weirdness goes up too. So, IMO again, for bigger planes, it's better to have a scale looking appearance (full fuse). The beauty of profiles is their simplicity. Ability to 3D well with standard servos at 4.8V, and any .46 engine. With bigger ones, this simplicity is lost. You need bigger engines, maybe even gassers, and high torque servos at 6.0V. So, for that, is better to get a full fuse plane. Just my 2 cents though....
