Blog News - Product Reviews and Help with criteria

Hi folks,
As previously mentioned a number of new reviews have gone up recently and have been added to the Book reviews tab. In the coming weeks I'm hoping to have some reviews on some products and sellers but the only problem is I'm struggling to come up with criteria as to how to review sellers and products. So far i have the following:

#################################

Layout for Seller Reviews:

Product Name:(This one's fairly obvious)

Production Company:(GW, FW etc)

General Summary:(A basic description of what the product is and does etc)

Review
Purchasing & Customer Communications:
(Rated out of 10- was it a smooth order process, did it come quick, was it well packed?) – out of ten

Packaging & Delivery:
(Write about the way the models were packed and does it show them odd to the buyer) – out of ten

Accutacy of Descriptions:
(Write about the way the models actually appear) – out of ten

Value for money:
(This should be fairly obvious) – out of ten

Overall Rating and Final Thoughts
(Rated out of 10)

These seem pretty comprehensive to me but could they be improved? Are there things you guys would like to see covered, are there areas I'm missing?
Any thoughts, ideas or comments would be really useful please folks.
Cheers
