It seems that they rejected it because of design. Did you mentioned in the comment for the reviewer (when you were uploading your file) that the HTML version was allready accepted? If not, drop a line to envato support on twitter and explain them that the HTML version was allready approved.
It looks a bit too plain. You can’t distinguish the main content from footer. You should do something about that.. There isn’t enough consistency in the layout. On some sections your headings are left aligned, somwhere they are right aligned and somewhere left. You should choose the alignment of the heading and stick with one of it. Services icons looks plain to. You should add more color to it, or some hover effect. Portfolio hover animation and icon need some work too. Just my opinion. Hope it helps. Good luck
