Setting business cards

Hi! I've sketched up a business card design but I'd like a professional eye to help get the balance correct and to work it up into the standards for a Moo business card print run. I need 3 fronts and 1 back designed.

I have vectors of the logo, font and the triangle pattern.

EDIT: The cards should be set to these specifications: https://support.moo.com/hc/en-us/article_attachments/202470674/UK_Business_Card_Landscape.jpg
Thanks!
