I realized that I had never finished off that Grey Knight squad which was so heavily converted.
All five were done using the same method... take a space marine, extend the legs and arms, and then get busy with brown stuff. For the finer details, green stuff was used.
I think an Orc choppa was used to create the Nemesis weapon.
And then to the painting!
Again, this was part of the unit that won my first Golden Demon (40K Squad category).
