Might as well chime in here as I've stumbled upon this by mere coincidence on Sideshow's website.
When Casey Love was mentioned, it dawned on me what I was looking at.
As others have stated, this did indeed start as a private commission way back in 2012/2013, intended for a handful of people. Most of them wanted it as an addition to the 1/3 Cinemaquette creature lineup. In fact I was amongst these people, but the project initially went nowhere/got delayed massively and I somewhat lost sight of it. Secretly I hoped (and still do) that Steve Wang would pick this up when ECC spun off from CM, but he never did for one reason or another.
Back then nobody gave a flying
about diplayability, the people involved just wanted the biggest, badest Pumpkinhead in 1/3 and the SS Maquette which also prominently featured in the Winston Effect was the obvious reference.
So, yes, I'd absolutely vouch for this having a traditional sculpting background and I'm absolutely floored to be able to add this to my 1/3 classic creature setup, albeit in a much different vein than originally intended.
From what I gather here and elsewhere, it would seem that some are also mightely ticked about this release. I can only assume what happened but hope nobody got seriously burned over this.
