What the....?

Only kidding. I see potential in this piece. Definitely rough around all of the edges. I give it a 5 for effort. You know what would have been funny, if the door opens and either the Detective, who is metal...that makes him a Metal Detector..no...if when he comes in the door and says :now, where is that villain?" he slips on "the fish" in the dark. or actually opens the door into the Fish, squishing him a bit behind the door. Comedy man...it's riddled with comedy. Keep working on it.

good Try

A good try,i cant do much better myself XD but do more practise and you could be a great flash.....man.3 for a good try

Keep practising

3 for effort. Try to familarize yourself with the program more. Example, It would have looked much better to use a guide layer for when the villian went was thrown through the window. There are plenty of videos out there showing you how it works.
While your still new, it's a good idea not to rush any work you do while you are still improving your technique, imho. I'm halfway through my first flash I'm submitting myself, and am currently on day 3.

Surprisingly not bad.

Every aspect of this animation needs to be polished, but it actually isn't terrible.
