I can give you the baseplate i always use. Originally, i used to draw minifigures' legs, arms, and torsos differently, until i decided to grab my Paladin concept art, turn it into a generic white minifigure, and then constantly use it for this stuff. So the only thing i actually am drawing is the details on the torsos, arms, legs, and hips.

Here's the art model:
