Additional Information
To me, wings - the symbol of rising. It also powerfully stands for freedom, desire, strength, and support. Thus far, I formed driftwood blocks to be the spreading wings with the implication of flying high to the sun. Starting from the main wings, leafy Hemianthus Callitriche, I trimmed it with care and passion to create vary layers for the feeling of smooth flow running through from foreground toward the sun. The wings are seen as the launching pad for the vegetation to rise up to the sun light. Besides, I chose an angle to capture the left and right reflection so that it can maximize the space for fishes to swim freely. In addition, I combined plants, such as Microsorum Pteropus "Narrow", Hygrophila Pinnatifila , and Lilaeopsis Brasiliensis in the composition to simulate the flow as well as give the impression of the feathery tips of the wings.
