Can you see Nasa's fine vertical pin? Notice how it seems to line up with important parts of the sculpture!
Also, I see over and over again the "wheel" of Curiosity selecting the lower right position for it's "wheel", as if to indicate that it is a favorite sculpture of theirs. It seems often when the wheel is placed like that, that the sculptures seems to pop out more, with more meaning and intrigue!
The analysis I use for the photos and imagery are not mean't to be exacting, only to get you closer to understanding that there is intelligent life on mars (martians). Many of the rocks you may think are rocks, are in fact highly designed sculptures, mechanical objects etc.
Nasa is trying to leak out anomalous imagery with out of course talking about it public! Though most images have been doctored, Nasa is trying to humbly and quietly nudge us along with out going too public about it vocally. Though it is work and painstaking effort to find objects in the images that have not been altered in some way!
