Niagara Falls Canadian side

Thank you for your criticism but you know the photo was taken around 17:30 and it was already dark for distortion, the photo was taken from the top of a tower as high as the Eiffel tower, thank you again for your advice: I send RAW photos so they can criticize me for improvement.

Your objective has a barrel distortion visible on the horizon. The image is dark, it would increase the brightness. I see a little dominant in the foam. Here you see the link to the tutorial on the subject.
