You know whatt i have to say, because i know you personally, so take this as advice for your next song.
First of all, dont place notes in random places, that will not make a good song.
Secondly, ( the way i make m songs at least ) make your song in sheets, that way, if you want to use that part again, you dont have to write it again, and with sheets, you can change tempo and it dosent effect the rest of the song
Lastly, spend time making your song, when you spend time making your song, you can edit it alot better, and get the feel of what is coming for you.
