Let's get you up to date with this guy...
I finished sculpting and prepared the mold walls...
...and started layering on the plaster
First the front half, then remove the dividing wall, coat with vaseline, back half, then separate them...
Then I made a core...
and finally did a pull in foam latex...
Lastly (at least, until I decide whether he'll get some sparse grey hair), ol' Zombie got an airbrush job with rubber cement paints
Not too shabby for a last minute job
