I need help with my business card

Hi, guys!
I need help with my template. It rejected( What could be the problem?
File PSD 300 dpi. CMYK
Each side in a separate folder in one file
Thank you in advance

hi this is not bad if u ask me, ttastefully executed i might add but the thing is , try to think about it, why would anyone buy this card? the style is rather simple and it would take very little to a professional to redo this, so they would not feel like saving time and buy in my view. Do not get me wrong, once again i insist on this idea, the thing is clean but maybe a bit too simple for here so to speak
