You can change the tempo of the song at the lower right corner of the editor. Your instrumentation seems okay, but it sounds like it could use a 3/4 time signature. Try placing the notes on the eighth beats and arrange them like you would a 4/4 time song.
Thank you for the feedback! I probably sound pretty stupid right now, but how many beats per minutes is a 3/4 time signature? I’m a little new to this.
