i know it’s really bad, i stink at this anyways 
First time for everything, right?
(Psst. You wanna know a secret? You can change the notes’ length using that button just above the instruments tabs. You should try it.)
It’s your first “song” (if you can call 2 measures a song), so it’s really not that bad. Don’t degrade yourself 
!
Also, when placing notes, put them on the line instead of the space. When you start adding sheets it will make your life a whole lot easier.
