Hello Jean-Francois,
Nice app promo video. Good job on the direction.
Might I add some advice to spruce it up, though?
First, add some music to lighten the mood. Many viewers get confused when they watch a video that lacks sound. You can find an endless supply of royalty-free music online to add to your video.
Second, make your message clear. This means changing the title to something more recognizable, like "Best Android Loan App: 'S Loan C'" In addition to making your message clear in the title, make sure to make it clear in the video! What does your app do? Perhaps add some narration or text to explain this.
Third, add a call to action. I like how you end your video with the name of your app and everything. But, I would make sure to put in a link to the Android app store so the viewer knows where to find it and what to do (download it!).

Hope this helps and nice work on your video!
