I adore this, so very much. I have always wanted to do this theme, and really wanted to do the bathtub with Lock, Shock and Barrel and yours is just perfect! I mean, everything is fantastic (Holy Moly - Dr. Finkelstein is AWESOME)
Only thing I could suggest is whether you've thought about having Zero flying? I bought a x-mas tree rotating stand that moves really nice and slow for something like this, and there are of course tons of great slow motors that you could mount Zero to (as long as he's light) easily to have him animated. Same thing for the Oogie Boogie wheel...
but never mind my suggestions - this is epic!
