Since I've been focusing so much lately on making the production process tighter, last night I decided to loosen up a bit and give the cards a once over with the palette knife.
This effect makes the cards feel a little more natural and loosens them up. Also, I believe it helps give them an air of mystery and intrigue, while keeping your eye bouncing around the page. When creating interesting visuals, I believe the name of the game is variety. Now, go back in and add a bit more detail and realism...
