Please tell us the reasons for technical rejection

This image has been rejected for technical reasons. What is the reason? How can I apply again?

The problem is image quality

I would say your white balance is off. I guess the 'pipe' should be white, shouldn't it? In your image, it has a slight yellow cast!

You have to correct this and then resubmit. There could also be some noise in the blue background.

Thank you very much for telling me something special. I will study photography data and try again.
