I need help
Can anyone write me what is the quality standard for business cards. What am I doing wrong …
This kind of design is outdated. Wrong font choice, it’s just not eye-catching and interesting.
See here to get some idea what sells great: https://graphicriver.net/category/print-templates/business-cards?utf8=✓&referrer=search&view=grid&sort=sales
And see this https://help.market.envato.com/hc/en-us/articles/202821070-Business-Card-Templates
And about fonts: http://fontpair.co/ and this https://www.canva.com/font-combinations/
Hope it helps a little, good luck 
Hello
The font choice is way off.
No graphic elements.
You should add the job position of the owner, company etc.
The background isn’t needed. I actually use that kind of paper for some of my clients
