Orioncroft well done... good use of reduced saturation.
However just taking your fist shot as an example, the sea to the left is very low contrast compared to the brick on the right, so the eye pulls to the right more...
I would experiment with a layer of a nice single exposure (one of the frames you used to HDR) and blend/ layer it with the finished HDR and mask away the HDR portion of the sea, showing the regular exposure (which would be higher contrasting)...
This is not a criticism, just something that could open new venues for you?
