[WIP] Prop - Crossbow Revolver

MexInTex

Hello! Trying my hand at some hard surface weapon modeling with an idea that I had.  A reverse draw crossbow/revolver combination. I'm imagining some sort of Demon Hunter scenario where you need silver bullets and a crossbow bolt at the same time.
Here is my design sheet with references. I need all the critique I can get to get this looking as best as possible and as marginally "functional" as possible with no glaring design flaws if it were implemented in a game somewhere.

Here is my progress so far! Still hasn't been optimized of course, just trying to get the shape language and design right.
