Some feedback:
On the video:At the end of the video you could use a fade instead of immediately stopping the video.
On the use of fonts:If you want to give the videos a more professional look, you should change the font,
because the current font you're using doesn't fit the narrative of the video and feels out of place.
You can easily find free fonts on
http://www.dafont.com for example, but there are many other sites.
Some examples that could work:
Bebas Neue (Very popular and works well in most scenarios, is compact and easy to read on a moving background):
https://www.dafont.com/bebas-neue.font Roboto (A font that has a rich typeface to choose from):
https://www.dafont.com/roboto.fontRenogare (A clean stylistic font):
https://www.dafont.com/renogare.fontThe 27 Club (A nice compact, readable font and good on a moving background):
