Inspiration : The primordial rainforest of West Africa is an unknown and mysterious region. The land which has suffered from poverty, enslavement, disease and war is almost forgotten by the world, however just like the prosperous growth of African aquatic plants and the proudly swimming 'phenacogrammus interruptus' in the Congo River, it is full of strength and vitality. The blazing sunlight refracted on the shimmering water bottom and life bloomed brilliantly in the deserted and barren West Africa land.
