Well, that was fast. Weren’t you just asking how to make a video in the first place?
At any rate, we generally don’t critique videos unsolicited. However, during our community events, like our livestreams, conferences and workshops, we often look at community submitted videos and give our thoughts. If you want to hear what we think specifically, we recommend attending these events. If feedback from the community will work, try posting your video in our forums and asking for feedback there.
