For a fake messiah, I'm not quite getting that. It lacks any iconography other than the scythe, which traditionally means death, and the rosary, which is more a tool of exorcism. As it stands I get more of a deathy purifier vibe off it, a spooky helper of spirits passing from one world to the next.
To run off christian symbols, for example, you could toss in a fake halo (like perhaps an anglerfish style growth), stained robes, preachy gesturing like raised open-palmed arms, maybe even multiple!
I can go on, just from that you can pull a lot of ideas if you really do a bit of thinking. Keep at it!
