Nice … a few offhand comments …
(1) Don’t start with anything that is “out of focus.”
(2) It isn’t obvious what the “trailer” is supposed to be about until the end of the piece. Let that be obvious from the (now razor-sharp) sequence at the start, which matches the one at the end to bring obvious closure.
(3) Your reel quickly takes off on a “visual story-line” and carries it through consistently, except for three or four seemingly-obligatory 3D models that rotate a couple of times. This disrupts the story, so cut them out. It’s clear-enough that you are adept at doing modeling, e.g. from the “frog popping-in and popping-out on a track” sequence that occurs a few seconds later.
(4) Once you have established the story and set the pace, stick to it. Remember, everything (especially anything set to music) has a certain “beat” to it, and each new visual surprise needs to fall “on the beat.” The story needs to introduce some surprises from time to time, but also to present surprising re-use of stuff we have already seen, which you do rather well with the frog. “The frog” invites the viewer to follow through the action from the point of view of the frog, or at least to use the frog as a tour-guide in a little journey full of surprises. It also provides continuity.
(4a) I don’t think I’d keep the “play buttons.” When they came swimming into view, sharp in-focus, I was distracted… “am I supposed to push them?” It was not something that I had been conditioned to expect, plus it was something that does carry an unwanted conditioned-response: “I’m supposed to interact with this.” Make it fuzzy if you need to keep it, but why exactly do you need to keep it?
(5) Creativity is always a plus. I think I know what school you went to, and maybe some award that you have won? Anyhow, it’s a creative and original idea to use those “falling logos.”
(6) I didn’t see any bad-cuts in anything that you presented. Nothing jars the animation or “draws the eye.” That’s good, and it demonstrates technical competency in the best possible way… namely, “of course.”
(7) With further cuts and tightening, this reel is going to be twenty to thirty seconds shorter but much tighter and “crisper.” It should certainly sell you well.
