Create a mood board filled with various elements that capture the theme of water dragons. The board should contain a blend of elements symbolizing water like representations of rivers, ocean waves, and serene rain. It should also contain elements that symbolize dragons such as dragon scales, dragon claws, swirling dragon flight paths. Also, include illustrations of mythical dragons emerging from the water or hovering over it. The moodboard should capture the majestic nature of these creatures, their affinity for water and the raw untamed power they represent.
