I know some people own thousands of miniatures. I have seen the pictures. I am in the mid hundreds, even counting 2D pawns.
I have focused more upon sheer numbers, than upon having the highest quality. Most, but not all of my 3D miniatures are Unpainted Reaper Bones. Most of my painted miniatures are Dragons, or Dinosaurs.
On my Unpainted Minis, I have at least highlighted the blades of their weapons, their horns, their claws, their teeth, etc
