Critique my companys site please!

I design websites as a hobby more than anything but I’ve recently redesigned the website of the company I work for.

Take a look around the site and let me know what you think, what you would do differently and in what direction should I go in to make it look and navigate more professionally?

Thanks guys - I trust you all will be brutally honest with me! (but try not to be too harsh!:trout: )
