You have all the shots and elements that you need. Keep watching it a few times and you may start to see small and sometimes large mistakes that you made, now is the time to fix them. I liked it overall but I personally would have left out a few shots or maybe rearranged it differently. 2:30 is an acceptable time but I would have trimmed it down even more. Always strive to keep your videos short, what we love actually bores other people to death. I could show you great shots that I thought were awesome and others become disinterested after 10 seconds. Overall this is a good effort and good enough like it is. I like how you kind of told a story with the climbing of the stairs etc. Was that a vertigo effect in one of the shots? I would have left that out. just because you got good footage doesn't mean it has to be included. I have made 1:30 min videos that I had 40 minutes of great footage to choose from. Getting your point across or telling your story without boring the viewer is what's important. Nice work!
