This thread should be in the GraphicRiver Authors section, not in Customers.
In terms of feedback, I think the spacing and alignment of some things look off, such as the text too close to the footer, icons not lined up properly with the sections, and there doesn’t seem to be much of a flow or hierarchy, each section should be grounded and defined, right now they look tossed in and just floating, if that makes sense. The abstract shapes could also use some work, for now they look very flat, which makes the overall flyer quite flat and uninteresting.
