Just a few comments ...
I'm assuming you are not finished with it due to there is no business name/title?
Also, are you going to add the two other icons (Samples & Contacts)? Because I would recommend that you do if you hadn't planned on it, otherwise, some people may not think to click back on the main menu icon to get to those pages.* edited
- I would, also, put them in the same order (meaning, the icons should be in the same order they are listed in the menu, or visa versa)
P.S. You have the "Quote" icon linking to the "Contacts" page.
