I felt like the island was missing something. It needed some different colours to attract the eye. The island was more of a bleached yellow than a sandy colour as it fit the style guide better. I opened Maya and began modeling some small rocks. I felt like i only needed a few as once they have been rotated and scaled they look like different rocks.
The style guide is low poly. This meant that the rocks did not need much or any real attention to detail. I made a cube for one and extruded on side. Scaled one face on on side and beveled particular edges giving it a cool stylized look. I wanted to make another rock look more like a sedimentary rock. I wanted it to be more flat, more like a sheet of slate. the first one looked more like a boulder.
