The quality of the sound, instruments is really good, it's neat, it's not saturated, it's enjoyable. I find the cyber theme really well done, the sounds you've picked are good choices. The constraint you've put yourself (no F) is fun to hear, I like ideas like these. You use the panning very well, I like the bass wave on the left ear and some percussions that are played at the center and the final notes in the right ear, it uses the full capacity of the space.
Maybe one thing that I could've been even better is if it had a crescendo that hypes us up into a big final, without necessarily removing all the credits vibe it has. For example, my favourite part is from 2:22 to 2:45. Before this part, we have this nice repetitive leitmotiv and it's the center of the attention and is played in staccato but when we come to my favourite part, it plays in legato and I find it very satisfying, the transition is well done and with the addition of the leitmotiv at 2:34 that is not played in full, therefore we expect more and more power into the music and we want the follow-up of the music. But I wished that this method (playing melody 1 in the first half of the bar, playing melody 2 in the second half of the bar behind) would have been used in the ending, I think it would have added more power.
But this is really high quality work, I took pleasure to listen to it !
