The strategy for the ISLAND

well, i am going to use the letter G and number 4 as the base figure of my island which i am going to show the shape by using the plants with different material and colour and I am trying to make it natural.
Also I plan to create the letter G part higher and number 4 part lower to set a drop structure. lastly, there should be lakes on the island at the centre of letter G and number 4 then I think will be a  more natural way to show the shape of the combine of G AND 4.
