Robot Arm Animation Critique Response

Comments I received on the animation: 
I received several comments on the general atmosphere or 'feel' of the setting I created in my animation. I also received comments on the 'floaty' keyframing of the camera. Furthermore, I received comments on the repetition of shapes (circles, lines & squares) utilized in my animation. A fair amount of people remarked that the setting felt as a ship in outer space would, rather than the empty office building I was attempting to portray. There were also multiple remarks about the storyline that somewhat diverged from what I was actually trying to depict.

What I feel I did best:

I feel as if I did well with the color scheme; the blues and grays used in the room and on 0R10N contrasted the redness of the Ominous Floating Cubes. I also think I did a better job with the storyline as opposed to last animation. The camerawork also seemed better, though still not great.

What my classmates said I did well:
My classmates said I did a decent job with giving the camera a 'floaty' quality and building up an interesting scene that utilized a repetition of circular shapes, which contrasted the squareness of the book and the Cubes. They also said I utilized some different angles for my story when it came to camera.

What I feel I need to improve on:
Animating a bouncing ball's movements to look realistic has always been one of my weak points, and in the animation it definitely shows. I also think that I should budget my time better. Furthermore, I felt as if my story did not come across well enough and that the ending was rushed, especially the keyframing. It pains me to look at it. Additionally, there were a few technical errors where you could see the endless void beyond the scene as well as a part where the camera briefly goes through an object. And the keyframing for 0R10N walking towards the window at the end... It looks like an ant helplessly flailing around in a pool of bug spray. I don't like that at all.

My strengths and weaknesses & a plan for what to focus on during future projects:
What can I improve?: So sure, the scene was built alright, but the problem was that people easily misinterpreted it as being in outer space rather than the woodsy night setting I had intended. So I need to build up the setting and character(s) with more consideration to what kind of theme their traits lend them to. I think that I also need to make the storyline not too complicated; I have to find the balance between detail and cohesiveness. I should also scrub through animations once I 'finish' them before the final render just to check for minor errors. Sometimes I get fed up with not having something done and just do it without thinking, kind of like chugging a Monster Energy at 3 am. Not that I've ever done that or anything. I should also work on pacing.
What are my strengths and how can I make them even better?: I like to think I'm pretty creative, so maybe I could lend that to the animation more. Rather than 0R10N throwing random spheres, what if it had thrown missiles? What if the setting was something different and way more interesting than the boring office idea I had originally come up with? I could've gone in so many different ways but I think I just caught an idea and stuck to it, but next time I should keep my mind open about it, since the first draft is not the final draft.
