This is a great MOC! I love all the details and stylish building. Just one thing... you got wrong the name of the explorer, it is Hernan Cortes, unless, you are making kind of your own story with your own characters.
Excellent diorama with lots of detail. I particularly enjoyed the creative use of the jumper plates for the adobe style roofs. The rugged shoreline with the cave provides a sense of depth and elevation change often lacking in dioramas. The graduated color change of the sea crashing into the surf is a nice touch. Lots of minifig action is also key.
