Ghostbusters

Ok, I have been putting it off for too long and now I want to get back to one of the first thing I started last year, the Ghostbusters poster. Admittedly I chose a difficult one to create a 3D version of when I was still new to learning Blender. Now I feel a little more confident, I would like to get back to working on this Ghostbusters project!
