So I was a huge BG1/BG2 fan, but graphically one thing that bugged me about the Infinity Engine games was that all the characters looked the same. Granted, with the resolution and isometric perspective there are limitations, but one easy way to add visual variety is to have varied body types--morbidly obese, heavyset, normal, skinny, gaunt. And different heights. When everybody has the same body frame and same height it looks rather generic.
