Design Bootcamp - Drawing a Blank

I had made this one for the bootcamp but "someone" ran off with my camera and I couldn't get it posted.  This class was discussing white as a design element and not having to cover the whole card with color or pattern.  Giving the eye a resting place as well.

Here are two attempts to use white on purpose in the design.  This second one was going for a simple masculine look.  The gold strips have a nice shimmer to help it make it have a more architectural feel.
