Wow, really good work. It makes me want to go back to Cabo. A few comments:
2.) I like the concept of the converging lines, but the gate across the front ruins the shot for me. I would have liked the shot if it was taken on the other side of the gate, letting the stairs lead your eyes up the shot.
3.) I like the pool scene, and the contrast with the dry hillside. Not sure how to make this one better. Something seams to be missing, but not sure what it is. Good capture though.
5.) In my opinion, there is too much foreground, and it doesn't add anything to the picture. Maybe try cropping some of the foreground out? Good colors and light.
