Why My photo didn't accept?

IP violation. Lighting of the Eifel Tower is protected. The phooto is overexposed which caused star trails and loss of details in the highlights.

This is one of the clearest IP violations I've seen. The Eiffel Tower by night is copyright protected. In addition you also have multiple Quality issues.
