My BC it isn't at the quality standard


my 2nd business card has been rejected. because it does not belong to quality standards.
I do everything with Aİ, only previews and thumbnail with Photoshop
thumbnail 80px x80px is very small so the example is a bit blurry. I think this is the problem. can I have advice please

I think this is so simple and not use any design shape to more make creative.

This can be done in 5 minutes without any design experience.

sorry but where can the preview be seen?
