Needs a lot of work.
Sounds like I did when I first started making music.
In other words, you still have a lot to learn.
You might want to learn some chords/scales and grab some new VSTi's such as Synth1 or Magical 8-Bit.
The ending notes definitely sound out of whack.
Sorry I can't be more in depth. I too am not a master of music yet.
