Rejection due to quality Issues

[PNG Store]

Some of my files are rejected due to quality issues. All my images are around 8k so i belive quality is not the issue on the other hand i think i should edit the colors of my images and a few other edits. Can someone give me any advice or tips on what i should be doing to avoid these rejections.

Well, if they got rejected for quality issues, the chances are high that there are quality issues. Again and again, as I have often stated here, the asset's resolution is not a quality mark. 

If you want a hint, why your asset has been refused, you should publish the asset here, in the same quality and resolution as submitted. Do no downscale, add watermarks or anything else.

Quality comprises much more than just file size and resolution. Some of those quality criteria are stated in the rejection explanation that you received: "Common issues that can impact the technical quality of images include exposure issues, soft focus, excessive filtering or artifacts/noise.

We always need to see the rejected assets here, at full size as originally submitted. It only takes one error to result in a rejection, and we can usually locate one or more.
