Okay, first of all, not terrible... You do have a fairly competent and finished animation here.
Might suggest something to do with frame-rate. It "feels" a little bit... "all over the place" (if that makes any sense)... Now, I can understand if there's something involved in connections and uploads versus how you "preferred" the thing gets presented, but it's still something worth mention as I think a slightly higher and more fluid and consistent frame-rate would improve the over-all experience of watching this.
Not sure I would have stuck with the "techno" theme throughout the work. Audio is a tricky beast when you decide you're going to incorporate it. As cited many times already (and I will continue to cite them in the future) Cinefix (on YT) points out that where the visual walks right through the front door of your eyes to your conscious mind, Audio sneaks in through the back door of your ears to your sub-conscious mind. The two work together (when done well) to create a whole new and powerful effect. So as long as you're going to the effort of a four minute presentation, taking the little extra time to pick and choose the moods and switches through the soundtrack to augment your intended emotional connection with the audience will only be a greater and more visceral impression achieved for your already impressive efforts.
I will kick around that some of the artwork involved was a little primitive in trying to "sell" me the views of an Exploration Mission craft heading to a different planet. I do kind of get that from the beginning (like in the title and description) but a little more attention to those points might really help. I also get that it's not exactly like art is a skill you get like math... either you can or can't do it. It's another of those skill-sets that works more like a road than a static place... So not to kick the dead horse about it, I've mentioned where you'll likely see the most improvement visually as well as audio wise (in my opinion) and I'll move on.
Again, and finally, you do have a decent piece of work here. I think you're reasonably skilled with the software and general techniques, so you keep practicing and you'll keep growing as an artist.
Don't forget to breathe, relax, and keep on keeping on... animators animate. :o)
