If these two images are your main photo and the supporting photo, then there are some obvious problems.
The supporting photo should always include the POI. I cannot see it in there. It isn’t officially mandatory, but it is extremely rare for there to be a good reason to avoid including the POI in the supporting photo. (I recently scrambled over a drystone wall with barbed wire on the top in order to take the supporting photo showing the view and the bench for a bench-with-a-view wayspot, because the bench was snuggled right back against the wall and it was impossible to get a decent photo from anywhere other than from behind the bench.)
Secondly, the main photo has junk in it - the chairs and table are not relevant and get in the way of showing what the POI is. I can’t actually tell form that photo that there is any water involved.
You may need to take the main photo at an angle, whatever works best to show that this is a water feature.
