Element found in Redang Island

During our mid-term break, we went on a 4 days 3 nights class trip to Rodeo Island which is now known as Redang Island. It is actually a combination trip for both subjects, Interior to Design Project and Design Communication. We are guided by Mr Redzwan and Miss Norji during the trip to help us explore more elements on the island that we can used to enhance our creativity. In this trip, there weren't much drawings involved, but we were asked to sketch out one of the element we found on the the island. Below is my sketches of Stacking Pebbles I found interesting on the island.
