Design a powerful and emotional thumbnail for a "Krishna Sad Story

Design a powerful and emotional thumbnail for a "Krishna Sad Story" video in a realistic style. The image should depict Lord Krishna with a sorrowful expression, his blue skin slightly dimmed to reflect his sadness. He should be wearing his usual yellow dhoti and a crown adorned with peacock feathers. Radha should be shown beside him, also with a melancholic expression, dressed in her traditional attire. The background could be a dimly lit, serene setting in Vrindavan, perhaps by the riverbank, with soft, muted colors to emphasize the somber mood. The title "Krishna Sad Story" should be prominently displayed in bold, elegant text at the top or bottom of the image, with a slightly distressed or shadowed font to match the emotional tone. The overall color palette should be subdued, with deep blues, grays, and muted golds to convey the depth of emotion in the story.
