Just my 2 cents worth. Ignore if you think it's nonsense.
1)What's the focus of this picture. It seems pretty busy. When i look at it, my eyes start searching for a focus point.
2)Having said the above, can I know if there were waves? If so maybe you can slow down your shutter so as to capture movement of the waves, even the movement of the people.
3)There's a pole sticking out @ the bottom right hand corner. Maybe you can PS that away.
4)The horizon seems a little tilted, you can adjust that in PS too.
Again, these are just my opinions.
