I also found a cyborg face. I have never found a half tech half alien face before so this was very unexpected and exciting. It means that alien on Mars did integrate technology into themselves, not just around them, but in them.
The size of the ancient artefacts and the huge number of them in this photo really blew me away. At first when I looked at the photo, it looked boring and empty, but on closer inspection I found a flood of evidence that Mars once had a thriving intelligent culture on it.
