I watched/skimmed the first two minutes of this video. The lack of audio seems off-putting and amateur (so does the Big Head). It also seems a lot like a video of someone filling out a form. I feel like most people will be able to fill out a form without needing a video walkthrough and the video walkthrough doesn't really convey the usefulness of the product - which should be in the very beginning of the product.

I'd expect an explanatory video to have audio, and to cover the core utility of the project.
