Kept my attention, just about
As others have pointed out, the robots attacking humans is really old now, so it is up to people to put a fresh spin on it. You haven't really done that, but it still remains an entertaining piece.
I hate that style of music, but it works very well within this. With more time and a hint of a plot, this would be a very good music video. As it is, we have robots chasing and shooting, with no real story.
The drawing is original, if not mesmerising, but it works very well. The whole style I enjoyed, and the pacing was fantastic. I don't think a single scene lasted more than maybe two seconds, it must have taken forever to draw -- kudos on that!
I didn't like the ending, it seemed like ED209 from RoboCop mixed with some sort of Matrix character - or was that the point?
Good work, but with more effort could have been great.
