Help me find out why? My Lightroom Presets were declined.

The email they sent me said:
“unfortunately we found it isn’t at the quality standard required to move forward, and you won’t be able to re-submit this item again. Visit our forums and ask fellow authors for feedback. Our helpful community will be glad to lend a hand.”

How can I improve my work if I do not know what exactly caused the rejection?

This was also rejected. Why? :disappointed:

hi, i am not an expert for this … for me, the result looks good, maybe u should try to check what the best authors in this category do and maybe try to contact them for specific advice about your item …
