Well two images and no set-up (nothing explaining them) means that we don't know the progression of the scene. So based on images alone, this is my first impression:
Pic 1, the gun grabber.
First thing I noticed was the harsh shadow. Facial expressions look ok, but I don't know what's going on to know if they are right for the scene. Gun to face and finger on the trigger is alright. I can see the shadow working if it's a fast scene. Like if the gun grabber pushes the guy or pulls him into another room. I would use a difuser on that light to cut out the harsh shadows.
