Always like helping new artists.
First of all you are using raw samples. It means you used sounds that are included in FL. You should addapt sound to create your own style.
Second you have no real melody going on. Try to make a good melody before trying to make a full song. Practice on it. Try different keynote lenghts and experience with pitches. You'll pop out a good melody before you know it.
Its always good to look up some beginner tutorials or guides.
