I took a look at your vid and here's my input. I've made a lot of training and exposition videos. This was an exposition video (showing some capability of what a company, etc. does) but it looked more like a training video.
Now your technical skills concerning the look of the piece were very good. Though there were places in the shop where I believe you could have opened up the exposure a half to a full stop to keep a consistent look throughout.
I liked the music but don't think it fit what you were trying to convey. What would have helped was a much tighter editing pace with close-ups on both the workers and the action timed with the music.
Your use of the crane/dolly/slider shots lent a professional polish to the video, but eventually were over and under utilized in places. The timelapse was a nice touch, but the pace was killed when you switched from timelapse to a normal-time shot of the cutting tool and back to the timelapse.
Most important, though from what I could surmise the vid was about a fabrication shop at the SDZ. Yet, your shots kept the focus on the machine doing the sheet metal cutting and that big manufacturer's logo gave me the impression that this was a promotion for that and not the SDZ.
Lastly, you had the 'Made in America' at the end and my question was, "What? The sheet metal cutter or the parrot pattern? Since you didn't show the workers completing the parrot at the end, it left me thinking, 'okay that was probably an ad for the cutter not for the fabrication capacity within the SDZ.'
Your work is definitely watchable, but you do need to work on your storytelling. This was a corporate video style shoot if I ever saw one. Corporate clients are notorious for not being creative, which is why they hire people like us. The stories you tell concerning their products and or capabilities have to be very direct and clear with strong beginnings, middles and endings. This one started out strong and got lost at the end. However, this is something that gets easy to improve upon as you keep going.
All together you did good work. Just consider the things I mentioned so you can make adjustments for when you do your next one.
