Ok, since you said you'd like to give feedback, here it is, but before you read any more, please take note that this is
constructive criticism, designed to help you improve your videos in the future. The text near the start saying "#HazeRC Montage" looks slightly unprofessional due to the black colour of the main text and the white stroke around it, it looks as if it had a white background that was poorly removed, so I'd probably just leave it without a stroke on it

Also the gameplay within the montage looked slightly laggy whenever you were shooting. The transitions between the clips is good and flows well. The thumbnail of the video could probably do with being better, since the thumbnail is pretty much what causes people to click on the video and watch it (The title comes first though, obviously). Also if possible I'd suggest having the music transition/fade in to silence, instead of just having an abrupt stop like you did at the end. Overall though, it was a good outcome considering you did it on iMovie

Keep up the hard work man!
