Easter Island-Like Statue Next To Heart - Are Martians Sending Us A Message?

As I have written in my other article (link) there obviously existed a civilization on Mars that ended up in a catastrophe which for the most part wiped out the surface. What is left many thousands of years later looks to be a planet still continuing to struggle without much water or atmosphere.

What we see here in the photos below is what looks like an Easter Island statue and a heart next to it found at PIA 18473. Perhaps a message from the Martians?

Not far from the Easter Island head and heart on Mars appears to be another carved face (head) underneath which appears to be a swirled pattern in stone akin to a Grecian column. (See center of following photo). Enhanced:

Here is another cliff with what seems to be a face and structures from the same NASA image – PIA 18743. Can you see the face carved into the mountain and what seems to be a castle to the right not far from it with a large circular entrance?
