Can you help with a Business Model?

After being around different systems, process, models, process tools, etc, etc   I wanted to try and see if I could design a model that would illustrate how it all fits together.

I have done a draft in Powerpoint,  this gives a good starting point  but I would love to get some feedback or other input – I will probably need to change from Powerpoint to another, more appropriate media soon.   The model is based around retail/distribution with a small amount of production.
