Bumi Parahyangan promotional poster and brochure by Rittsu, at Behance. Triangles don& seem to be popular shapes to use in graphic design, but Rittsu executes them well here. Notice the subtle arrows pointing right to persuade the viewer to read on.
Balance- This poster is an example of symmetrical Balance using color and placement. The reds and blues are balanced vertically on either side of the page, while the triangular shapes are balanced diagonally in a reversed fashion on both sides.
