Looking forward to the real movie.
But, for now, let's just review the trailer.
Good:
-The artwork was beautiful. I think you did a great job with that.
-The animation was very fluid.
-The music you selected gave it a really epic feel.
Bad:
- The action feels to slow. Not necessarily what the characters are doing, but what is on the screen. This is especially prevalent in the Clown/Hank fight. You should try zooming up in on them and adding a more dynamic camera to add more action.
-Hank's head is to small, making it look un-madnessy.
-The gunshot at the beginning looks strange.
-Just as a personal opinion, you should change the placement of the text. to build more suspense, you should instead have it as "Krinkle's mind" then "Is a world" and then, right before the change in music and when the clown's mask falls off, "Of MADNESS". That simple touch would make it seem more like a trailer.
As just a simple flash trailer:
