Notice how the fore-finger (top left) has "white" markers on it! Often if you were to move your fore-finger, you would in fact move along those paths that are fashioned with those "white"makers. Included your wrist, if you were to use it as you moved your fore-finger! Notice how the "arm" lower right, has "white" marker, seemingly because it is represented as moving along an appointed horizontal path.
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!
