Hi, please help. I had uploaded few images and most of them were rejected due to image quality. I didn't over edit any, and purple flower and the tree bark, were taken in a professional camera. What can I do??? pls give any tips

The top three landscapes would have been better if taken in landscape mode. So composition is one of the issues.

Composition, focus, and slanted horizons.

Purple flower:

Focus!

PS: a Professional camera in this meaning is rather something like Canon DSLR EOS- 1D X Mark III

The first few appear to be cellphone snapshots, poorly composed with leaning horizons. The one with the seagulls has visible noise. The flower image also suffers from poor composition, and the last image with driftwood is blurry.
