This reminded me of Constantine. I mean, the idea of a saint who doesn't just sit around praying, but goes out and kicks some demon ass. XD
The humor was for the part where the guy was praying and the Saint threw that thing into his hand and mouth right as he finished, by the way.
The blood could be a bit improved - I don't know how to do flash, but I've seen animations where they've done blood splatters that I would have thought were professionally done. So I figure the blood could be of better quality. Other than that, there's not much to say about this except: good job.
