Erica is best known for her playful and expressive paintings, with a distinctive colour palette, incorporating elements from various cultures. In this scene, Erica brings out the contrast of golden colours of bountiful rice fields (indicating good harvest, symbolising prosperity), incorporating people, children, doves, dogs and cats etc. Full of joy and zest for life, her paintings are observations of the intricate relations of man, local traditions, and surrounding environment.
