Sea view on a slant

We have arrived at St Paul de Leon on the north coast of Brittany, in preparation for our ferry back to England in a couple of days.
This campsite was recommended to us by the couple that also told us about the Ile de Re. It is a shame we didn't talk to them for longer as this place is also excellent, and we are always on the lookout for tips.
They said to get here early and try to get a sea view, and here we are, just a few metres from the waves.
They didn't warn us about the slope, although it is probably more to do with the way we have parked the van. Or maybe we are okay and the horizon is at an angle.
