I felt the lines were too distracting and the flush primary colour was a lot more engaging. I incorporated the same degree of angle into the back of the card carrying the same concept throughout.
I also had to find a secondary typeface, to accompany the title. This took quite a while but eventually I whittled it between Futura and Beauchef W00 Book (Regular) and the latter was more suitable. The rounded glyphs worked well with the harsh title typeface.
I then went on to the letterhead. The client asked for simple stationary mock-ups, incorporating the brand into a letter head that would be sent to clients. I worked with the same angle. Rearranging the footers allowed for correct spacing and boundaries.
