Create a song with Piano -- 2

I have attached a file of Garageband and a MP3 where I need to resume the loop into a romantic and soothing song with a Piano and somewhat similar melody to https://www.youtube.com/watch?v=5cMR-ecida4 (suzume no tomari chewie melodies). It should start from the loop Skyline Piano, after that you can do whatever you like.
