in my opinion the promotion slider is too big. I use a 13" macbook and I only see 5/6 of the slider. Then, when I scroll down and see what the website is about, there is too much text. for my taste it's too overwhelming, too much info. I think the icons are great, make them bigger, shorten the text of each description.
Try to make the header images for each section a little smaller. Not so much in dimensions, more in size. They take up time to load and some people are left with empty space for a few seconds, they might leave early. As a general rule: show people right away (without scrolling and waiting) what they need to see.
I checked the homepage again. As I'm a slow reader and focused on the picture in the beginning, I couldn't read the slogan. The slider changed too quickly ...
Overall I like the design and colors. Keep the little gadgets like spinning social icons ;-)
