A huge friendly water dragon with iridescent teal scales rises slowly out of the lake beyond the ripples, water cascading from its horns and body, and gently lowers its head until its nose touches her outstretched hand; she smiles. The camera cranes up and back to reveal the dragon's full size against the dawn sky. One continuous shot, no cuts, smooth confident camera, consistent character, correct anatomy, no text, no logos, no captions.
