I like the design just a few things that seem to be off.
First the kerning on your logo doesn’t feel right to me.
2nd. Images look stretched as mentioned and arrows aren’t crisp.(http://abload.de/img/bildschirmfoto2014-07hoakp.png)
3rd. On the clients page you divide via a background image but still have divider lines. It looks like a bug.Look at where the image ends and white beginns (http://abload.de/img/bildschirmfoto2014-07sremq.png)
