Hunter's theme played on the piano

This is a video of me playing the Hunter's theme. I am playing it on the piano. It took me roughly 5-10 minutes to learn how to play the notes and learn the whole piece.
I learned about the placements of different keys on the piano and which ones to play.

1. Rhythm: I learned how to play the rhythm by listening to my friend and teacher play the piece and by studying the music.

2. Pitch: I learned how to play the pitch by listening to my teacher play and reading the music (where the notes are placed) and testing out different pitches on the piano. My friend also helped me learn the pitches.

3. Placement of fingers on Keyboard: I learned how to correctly place my fingers in the keyboard by finding a comfortable position and also by observing how my piano playing friend does it. I also observed my teacher's fingers on the keyboard.
