<https://s.mj.run/0HrCNvDO2Is> Create a dark-themed version of a circular logo featuring a bird in flight over a serene landscape. The bird should maintain its dynamic pose, but with darker, moody tones to give the scene a more dramatic, nighttime atmosphere. The background should be reimagined with deep shades of navy blue, dark teal, and muted greens, representing hills and water under a twilight or night sky. The sky should fade into darker gradients, with shadows emphasizing the contours of the land. Keep the composition simple and elegant, focusing on contrasting the dark environment with subtle highlights that create a sense of depth and calmness.
