Very Cool, very Ambitious makeup, I like it.
I used to have a grown up party every year, lot's of good food & creepy treats like sugar cookies shaped like human fingers: an almond slice makes a perfect "finger nail". A little red gel frosting on the end to add the yuck factor ...
I don't do so much now, but always carve a pumpkin jack-o-lantern that becomes pie filling later. And don't forget to roast the pumpkin seeds .... very yummy.
P.S. The scariest costume my son ever wore, hands down, a clown. Not even a scary clown! He got more people screaming with that outfit than any other!
