This is my 2nd opinion to BWarners photo "Casual Fridays" [link]
(original to the left, 2nd opinion to the right)
I really like the contrast between the red and the white and blue. I think the aligning between the flag pole and the tower is was nice choice and the antagonism between the calm and beautiful sea and the warning sign adds some impact to this picture.
In contrast to the original photo I focused on the tower leaving the flag pole just for bit of framing. Additionally I change the contrast, sharpness and saturation a bit and did a gaussian blur on the sky to remove some of the noise artifacts.
