Really nice work! I really dig what you have here; the effects work great and change well across the picture cuts.
All I really have feedback-wise would be thoughts on where you could maybe push it a little further. These might already be things you had in mind, but here’s a few thoughts
0:18 - On the two shots here of parts being put into the car, we don’t see any of the pieces quite lock into place, but I think it’d be nice to still hear things lock into place right on the picture cuts to the next shots. That’d add a cool percussive element, and also help enhance the feeling of the vehicle being assembled.
0:30 - Same thought for the cut here.
0:45 - I just wanted to say that this is my favorite part; I love the high-frequency detail on the wheel close-up, and how transitions into the wider shot right after. Great work!!
0:59 - I feel like the hand here wants some kind of sound cue. Even though it’s not realistic, something to illustrate the emotional connection the person (probably the driver?) has with this vehicle. It could be something like a combination of a cloth brushing sound and maybe a human exhale? It’d take some experimenting, but I feel like there’s a good opportunity to do something abstract here.
1:03 - For consistency, I’d love to hear the machinery here rising up, as well as a cue for the lights changing.
My only other thought overall would be layering in a bit more machine factory noise; I like the somewhat high-pitched steady effects you have, but it feels a little small for what we’re seeing, and for how epic the music is. A little room reverb might give it some weight, but some heavier, hydraulic effects might also help fill it out. Hydraulic stuff tends to have interesting pitch and “shape,” so that’d also give you an extra element to add some energy and motion to the visuals.
Awesome work; thanks for sharing!
