I didn't spend too much time trying to perfect the loot bag or the boots because I get a bit of miniature fatigue when I paint player characters. I don't have this issue with monsters...it is a weird condition so be thankful you don't have it.
The mini is supposed to look dirty and unshaven from being underground for a long time. Also, I tried to make his face a reddish color to indicate that he has been drinking heavily on the adventure - I know I would if I had to loot a dungeon full of monsters.
