its not a bad song though you could of done a little better
How to improve
It's obvious you can take a melody and put reproduce it. Now, make it interesting and put a new spin on it. Incorporate it into another track, make some new chords to play off of the melody, play with tempo - make it sound more like you instead of a basic transcription.
Please contact me if you would like to use this in a project. We can discuss the details.
