The visual quality of those assets is quite low. The materials look very flat, as if they aren’t pbr accurate. The tiling of assets isn’t hidden at all, and the trees in particular look very bad. Too few and too large leaf sheets. Because there are already assets on the marketplace that fill a similar role, but with much higher quality, my honest assessment would be for you to rework the pack and then resubmit when you are able to achieve a comparable level of visual fidelity to competing assets.
