I just listened to your track, there is much work to be done. The sounds from your keyboard are absolutely not "broadcast quality." Always listen to examples and reference files with a critical ear. Listen to the music in headphones and listen for things like how the different instruments are panned, the EQ, the quality of the instrument tones, the dynamics, the space between notes, etc.
Something you can do to learn your tools is try to replicate a track that you like. Find something on YouTube or Spotify, or in your own music collection, and drag the mp3 of that music into your DAW. Figure out the tempo so you can sync up to it, then try to replicate each part. It can be very frustrating at first, but the more you listen the more you will hear. Listen for the piano and how the patch sounds... is it soft, or crystal clear, or bright? Is there any reverb or delay being used, if so, how much? What other sounds are being used? Are there any little pieces of percussion or effects that you hear, sometimes called "ear candy" in the background? What is the man focus instrument during each phrase? What is the bass doing? What other instruments are there? When do they enter and exit? Take notes, draw out a timeline of the track using measure numbers or minutes and seconds. Study the style of music you like, listen to lots of it, put pencil to paper and figure out the structures of the tracks that appeal to you.
Have fun with it! Embrace the challenge!
