In addition to being quite underexposed, as noted by Michael, there is noticeable noise in the sky.
Your photos are under exposed (too dark). The quality is not good enough for Stock.
Adobe Stock customers expect the highest visual and technical quality for use in commercial projects — brochures, posters, video, TV ads, product packaging, merchandise (T-shirts, coffee mugs, etc...). Your images must be professional quality. See the links below.
Better luck next time.
