Coughin' Coffin designer, Nik Sardos, a.k.a. T16skyhopp, is a 2-D designer and animator. He said he liked the idea of making a design out of "nothing specific," referring to the creation of a character that's not much more than a conglomerate of stuff.
I love seeing the transformation of the character. Check out the more anthropomorphized version with the goofy eyes.
But here's the refined concept that Nik came to, leaving off the more "alive" aspects, and focusing on creating the character out of nothing more than exactly what it is. There's still a nice hunched over "heaving" motion to the design, which I tried to capture in my sculpt.
Here's one last picture showing how Coughin' Coffin will play nicely with your other favorite mini figures. To the left is a classic Monster in My Pocket figure and one of Alex Pardee's BUNNYWITH toys. On the right, we have a M.U.S.C.L.E. figure and a S.L.U.G. Zombie.
