On the left is an old man in armor. On the right is a guy with proportions so awful, he can't even fit in his own portrait.
Funfact: Boucheron (and the others) is actually modeled wrong. If you look at Mika's concept art for him, his armor is very different.

Congrats, you named the armor dude as your one example.
Unfortunately, the only armor dude among the ones list above was Louis, and then Jade was an armor girl.
There is no reason why Vander, Diamant, etc. should look like that. It was just a style choice the 3d modelers took, if you see the funfact above.
