For this assignment I used a picture from Pixabay.com that I think is matching the theme of my business card.
In Photoshop I used the Art Board.
For contrast I used light green background and black color for writing using different fonts and sizes.
For repetition I used the same typeface for the title and the subtitle, and for the contact information.
For alignment I tried to achieve the balance between the information and the image.
For proximity I used the rule of Square mentioned by McWade.
I made some corrections after getting a feedback from my instructor Nathan Smith.
I've changed the text direction following the book line.
