New Website Navigation Feedback

We're in the process of redesigning the navigation structure of our website and we'd like your help!

We've come up with two prototypes, and would appreciate your feedback.
Click on each of the links below to prototype.

Prototype 1

Prototype 2

Your feedback will help us work out if the new structures make sense.
This is not a test of your ability, it's anonymous, and there there are no right or wrong answers!
