I have a light box, I was just too lazy to set it up...The scene needs to be well lit, but without lights that reflect.
You want maximum diffusion.
A white paper diffuser on the lights will help a lot.
By the way it looks great.
Did you make a special punch to cut the hexes?
x-acto knife and the nut. I tightened it up to make a dent/impression in the wood then cut that out.
