Right arm sleeve including pectoral muscle

Right arm sleeve including pectoral muscle. On a male. Currently the bottom half of my arm so from the elbow down had an underwater theme. I want to design and solid black band themed coverup/sleeve. The design is mainly hexagons which are my current skin and the outlines are thicker Bold solid black. So the whole sleeve is hexagon spaces about 2 inches worth of tattoo design space. The idea is that different artist pick a hexagon and do their art in it.
