I imagine videos are pretty nerve wracking to shoot while urbexing (I only shoot photos)! And the video was enjoyable!
One thing I forgot to mention was that I didn't quite like how many establishing shots you had- especially the one at 0:57-1:00. You could probably cut down to just 2-3 from the 7 or so that you had. The amount you have at the end is nice (just 2 I think).
And the shot at 1:28, 1:37, and 4:24 seemed very sudden. Maybe a more gradual transition would have been nicer (like a fade to black or cross fade transition).
The photo at 2:26 was nice to show the smashed object, but it could have been better if you slightly zoomed in or panned the photo. It stands out in a bad way because it's static. And the sudden static shot at 3:22 felt a bit random as well. There's probably a few more things in the video, but generally, try adding slower transitions!
I also really like your abandoned power station video a lot! Seems like a really cool spot!
