Utopia Face (HiRISE MRO CTX image P04_002714_2144_XI_34N212W) 2007
Notice the oblique camera angle coming in from the left exposing the western side and distorting the rise of the cheek, while leaving the eastern side in shadow and foreshortened mouth feature which no longer has an almond-shape.

When compared to the original Viking image, there are obvious discrepancies between the facial features of the Utopia Face seen in the THEMIS and CTX image.
Not only is the lighting different in the new images, due to the time of day and orientation of the camera, but portions of the western side of the formations mouth parts appear to be missing.

Gary, thanks for finding this. Note this HiRISE image, like the last CTX image, is shot from an angle (off nadir) - coming in from the left side, distorting the "mouth". The only over head shot of this formations is the THEMIS image (V22286011).
