Well...
I'm giving you 7 stars for the gore and practicality. What I don't like about your work is that the story isn't really piecing together dude. The art and spooky element is supposed to be there and this "Mr. F" guy is pretty interesting, but seems to just kill with no motive. Which would be cool if he was just some guy, but it seems like he has a reason! I think the church thing was kind of just to get some religious hint in there for shock value more than story element. Oh yeah and your art is cool. I like the way you present things. I'll be looking for more of these hopefully with more story line then "I killed her. Here's her necklace. Now I'll kill priest guy and the nun."
You have two good video's for an entry to this disemboweling Mr. F, now we need some inner philosophy on where he intends to go with it. But don't give away his whole story! He's supposed to be mischievous. Unless you just wanted to make some Gorey videos...In that case, keep up the good work!
