+1 EP
+1 Vento
Vento's looks astounding, but it's hard to really see mafia vibes going on.
EP's is a good fit with the theme. Also, it has a joke, which is always a plus :U
Kaze: Not bad, but I can't really tell which Touhou this is. Tenshi? Not sure what her right hand is doing,either.
Desu: The situation you were trying to portray is pretty creative. A problem that stood out to me was the eyes - they don't have much emotion in them, and don't fit well anatomically with the side-view faces.
