I'd have to agree with the cutting the hiding, Go with more stabs, try to be creative, cut out the background noises(Ingame sounds, vent and the voices).
One spy video I saw was pretty cool, They used a variety of the watches, invis/DR/C&D, and It was pretty cool, made you want to watch more because you'd never know what you'd get for the next clip.
Otherwise not bad, You've got potential and everyone had to start somewhere.*cough FRISKY cough*.
PS: Chain stabs are win.
