I love the header image. The subtle animation of the satellite is a nice effect, and the shadow on the banner text makes it legible against any background colour. The squoval porthole-type image is a nice touch too.
I really like the way the form labels animate out but are still legit HTML label elements. I don't know if that's your design or part of material (after peeking at the class names) but it's nice.
On to the places I think you could improve:
The drop-down menus are a little weird - they take about half a second to pop in, which makes the page feel laggy, and I don't think their look and feel matches the rest of the menu.
Several of the links offer poor accessibility - for example the social links in the header are empty of content.
The blog posts in the footer could either disappear or have a heading, because at first glance it looks like the menu reads "Home", "Coffee Shops...", "Services", etc. which is confusing.
The "Sign up for 10% off" form on your login page does not have the same consistent label effect as the main page and uses a simple placeholder instead of a label which is bad for accessibility.
I agree with @rdumais
about the form widths and @phallstrom
about the voice. You say "My name is..." and "See what we have to offer" on the same page. Pick one and go with it!
The other pages look unfinished, for instance the contact-us page has different social link style and misaligned radio button labels, so I'm not going to comment further on those.
