As for as the "mouth" comment. The martians must have a reason to make things sort of look like a "dog face" but put something different in the mouth location. Seems as if they have a story to tell about half looking creatures looking like they should and the other half totally different! as far as us earthlings recognize things!
A Martian Boy Molded with Hands? I think there is a lot more going on with this image, if you look close on the top of the head there is other things, hope they are good things and not screws loose :) https://d2cj35nmzi9erd.cloudfront.net/msl-raw-images/msss/00952/mcam/0952MR0041900310502115E01_DXXX.jpg
The Leaders and the followers? On a ship or a type of vessel or compartment etc.? But with a flat surface! The faces seem to be be partially fuzzed out !

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!
