To be able to help, it would be great to get to know a bit more about your aims and the current process:

- What do you hope to achieve by the design-reviews? What would be, e.g., a huge issue which is missed?

- In which form are the designs delivered? (Photoshop files, Specs, Interactive Prototypes…)

From what you describe, it seems to me that people might be unsure about what they should do and how they know that they did a "good" review.
