Item rejected: Reason no well explained

Hi I received a rejection from my item but the reason is not so clear

Your item is rejected
App is rejected for the following reason:

Does not meet minimum quality/value requirements to be sold on the marketplace.

I was reading the Help Center and I'm not sure if this point

Icon and preview image do not meet quality requirement

If you submit your item, please make sure you include quality images. These include a icon 200x200 and a preview image 1600x800. Don't stretch images to fit these dimensions. Also make sure you take the time to create professional looking images that represent your product. Have a look at other successful items on the Codester marketplace if you do not know where to start.

Would be a great help to confirm to make the respective changes.

Thanks in advance.
