Liked the idea
Not the best of executions, but the idea was interesting.
I've actually thought of this concept often, and I've concluded in my mind that something similar to this is going to happen eventually in terms of engineering. I can kind of sense the presence of some uniquely incredibly innovative people on this earth (people who aren't well known), because hypothetically if you as an individual think in a certain way, you would naturally expect there to be others who share the same way of thinking.
But enough about that, this was good for a first real animation, the only advice I have is to work on your execution - which would involve reworking multiple elements such as the sound (I feel it could have fit the idea better, as it sounds overly desolate, though I do understand it was going for a dramatic feel), story (couldn't bring myself to 'believe' it, you know?), graphics (not really necessary to improve in this case, the graphics are sufficient as long as the other elements are improved on), and the animation (the flow, the style - the animation here seemed pretty linear and inexpressive to me personally, i.e. the motion, even though this was practically almost inevitable due to it being pencil drawn). To make this kind of thing reach its full potential, you have to instill as much meaning as you can into every little detail, as if you're weaving something together of which every component has a purpose - this way you create a short, thoughtful animation with huge impact. To perfectly execute this, however, you'd likely have to spend more time planning out the animation than animating it.
Well, that's all I have to share, good job on your first and good luck on your next project :]
