GHOSTBUSTERS - Adventure Map [Progress Report]

I've been working on this adventure map for a while and here's what I got so far. As you can see from my demo I released, my Ghostbuster's blaster was just a bow. I realised that I needed to be more unique in my map making skills, so I decided to re-work the way I created the Ghostbuster's blaster. As you can see from the picture, I'm pretty much finished the exterior. If you're interested in helping me with the map (build team needed), the map making process would be faster.
