This is exactly what my project 'Building Empire' is like, except with less (i think) behind the scenes material available. It really is a big job to get it all together and get it in the right place. The job then is to make it look cohesive with a natural flow - something that has been the biggest challenge.

Might I suggest to generate more interest for the viewer of your project that you put in an audio commentary from all the various sources.

Theses project really do eat up time, so be careful!

I wish you the best of luck!
