Asset Rejected: Image quality required

Symptoms:

• My package was rejected for the reason: "Image quality required".
• My package was rejected for the reason: "Contains excess image text".
• The vetting team has informed me that the marketing images must be improved.

Cause:

Your package may have been rejected because the vetting team found that your product's marketing images (key images or artwork) don't follow our guidelines or quality standards. 

Marketing images can be refused for the following reasons:

• The Unity default skybox appears in the key images.
• Images are too dark, or it's hard to see the product.
• Low-resolution or pixelated images.
• In-Editor screenshots are not edited to look attractive and intentional.
• Too much text is different from the package title, publisher name, logo, or a short tagline (this includes descriptions of package features or ornamental text that is too prominent).
• A lack of appealing color theory or attractive design principles.

Resolution:

Make sure that the marketing images you create are attractive to customers and clearly display the package content. You can see acceptable key image examples in the Submission Guidelines. 

Here are some questions to consider when creating your marketing images:

• Do my marketing images clearly display many or all product features?
• Are my images high-quality and designed intentionally?
• If I saw my product in a list on the Unity Asset Store, would it catch my attention?
