Letterhead Progression

I want these letterheads to not just exist, but also add to the image of the company. I would rather it were not neatly justified in the corner of the page with some neatly aligned type.

The continuity between the business card and the rest of the range will hinge on the composition of the designs. A partial view of the logo. It adds an arty persona to the company and lets people know they are not simply another company doing the same old thing.
