That is technically impressive, Hassaan, and thanks for sharing.
One recommendation: I wouldn't have the demo avatar saying things like "really cool setup you have there, and a great view out of your window". At that point, it feels intrusive.
As for what I'd build... Mentors/instructors for learning. If you could hook up with a service like mathacademy, you'd win edtech. Maybe some creatures instead of human avatars would appeal to younger people.
