You've definitely got some talent there. One of the most important things to learn about making a movie is that you will
never have enough money and resources to do everything you want in a movie. Even if you have a $300 million budget, you'll wish you had $400 million. The important thing is to make effective use of what you have, and I think this clip shows a real ability on your part to do a lot with a little. Limitations are what makes creativity possible.
One thing to keep an eye out for is focus. I worked for a film sales company for a long time, watching several movies a day, and nothing makes an unprofessional movie stand out more than shots going in and out of focus. I'm not sure what camera you're using to do this, but make sure you never use the "auto-focus" feature. It gives everything a "home movie" vibe. That said, you have a great eye for filling the frame, and the writing desk shots, for example, shows some great improvisational production design.
You're off to a good start on filmmaking. Like I said, I've watched
a lot of independently made movies and trailers, and I've seen a lot worse from people who claim to be master directors. Keep learning and finding creative solutions to limitations, and when you actually do find a little bit of money to make a full movie, you'll be ahead of the pack.
