Yeah, I'll 'Dive in'
Morro Bay is my favorite beach. I've been to that spot many times- to fly a kite.
1 & 4 out of square.
3 would have more story-wise it if the half-people were cropped out along with the mother and child (?) on the left.
In 2, the leg of the gull is in line with a scratch on the rock. To me this bisects the photo.
4 looks interesting and would probably be a better picture with the framing rocks and the surfers in the distance cropped out. Make it more about the kayakist.
I hope you get to go back. Aside from being beautiful and quiet, photo ops abound. The jetty at the other end of the rock from where you are standing is a good place to get shots of the waves breaking (just don't go out on the jetty, it's not worth getting hurt). Behind where you are/were, on the bay side, otters swim with their pups in their arms. The sand bar protecting the bay is also a wildlife refuge. You can rent a canoe to get out there at the parking lot at the west/south end of the embarcadero. The docks are also cram-packed with photo ops as the bay is primarily a fishing bay rather than recreation. A hike up Black Mountain (drive through the golf course) produces beautiful pictures of the south wetlands and bay as well as the rock from high up.
Places up the (north) coast a few miles are the little town of Harmony (pop. 50) and the Sea Lion Reserve on the beach right before Hearst Castle (San Simeon).
Even if you can't make it back, keep trying. Being someplace with a camera and working the variables is the first step.
AND- a final note. Remember the 'golden' hours, at dawn and sunset. For my tastes, a serious outdoor/landscape/wildlife photographer should be out there. This is when nature happens.
Best-
