Unoriginal and boring
I am sorry but this was really unsatisfying. I am sure you have enough imagination to power a good brainf* showreel. But there are just so many points you have done bad:
1.) Overall very predictable and unoriginal.
2.) It just seems to me you keep repeating the same theme over and over again.
3.) The animation was good as an animation can be, but the design just doesn't fit. The background was too detailed, you easily get out of focus, and here we go to the next point...
4.) Timing. You lose your focus once and you'll never see what happened. I am quite sure this was bad due to the music. Make your own catchy electronic music to fit the showreel, not the showreel to fit the music.
5.) Copypasta. Is it just me or is everyone else feeling that you saw this once already?
Overall, Cyriak is so much better. I give you 4/5 and 6/10 for trying.
