The piece is beautiful in the way the rocks form together. The style is unique and gives it a 3d look. 

The artwork depicted is different from the rest because it is more intricate. The linear strokes are cohesive like the bottom piece. The beautiful sunset and the ship make a comfortable aesthetic feel. 

The artist was trying to express the different colors and how they combine though this art work. When the colors combine they form new ones and the streaks express the flowing pattern.
