Come up with an arm.
The shoulder socket has been magnetized. For Arm swaps.
Added a tail to make the model a bit more menancing.
One of the comments was that the disc looks too much like a 40k Tyranid (not a bad thing in my opinion) and another was what about a tail. Then as I was working on the knights I saw the musician’s horn.
So, that led to a slight change in modeling to where I came up with this. And you guessed it, some of the horns that I cut off the knights/chaos warriors heads make an appearance (don’t throw anything away).
