As a Follow-Up to Danielilo's excellent answer and to reply to OrangeDog's comment.
The original is obviously not done like this, because all the "scales" are different
You can achieve almost exactly this with a few more steps.
To achieve even more non-uniformity than just roughening them.
Start off by ungrouping all the elements and then you can use Transform Each (Alt+Shift+Ctrl+D)
One more step further you can perform a Transform Each on the individual components (swoop and line) to further control.
