I think it's easier if I point things out in bullet form, so here goes:
-The dotted lines separating products are inconsistently placed, put them all in the same relative places because the images are all in the same place anyway
-The ///// design feels tacky on a white background. I would opt to replace its use with a solid design, if anything at all
-You alternate between angular and rounded elements with your boxes. This is actually pertaining to the black boxes at the top and the /////'ed box surrounding the other content
-The featured news posts aren't spaced correctly across the box (not sure if that's intentional). At least it "feels" like it should be evenly spaced out unless there's something else to go to the right (like a scroll-bar, etc.)

I can't say that I'm a pro at design, but those are the things that caught my eye.
