Dont Worry Be Happy Intro Tab

Hello out there! For everybody who's in a bad mood I tabbed out the whistling
melody of this legend song.
This is my first tab ever and I tabbed it out by ear.
You have to watch out for the timing but I'm sure you'll figure it out.
If you have any ideas to improve the tab, please feel free to comment.
 
The tuning is standard.
