Thank you @dostovel for that elaborated and thorough response. You are right: I payed special attention to shaders and textures, trying to imitate the texture of a granulated piece of paper for a business card. I also played with the depth of field an all the distortions that a camera has… but the colors, as you stated, are really vivid. Probably I should make the color of the card more in touch with the sunset atmosphere. What does @spikeyxxx think?
