hi, I am relatively new to grasshopper and am trying to create something that looks like these hand drawn images


so far i have tweened two curves in grasshopper and divided those lines, however, i can’t figure out how i can create smaller lines parallel to the tweened curves from the points created from when i divided the curve? when i have tried the lines either do not appear or are crossing all over. i also want to randomly scale each of these lines from their center point as well as slightly rotate them randomly to create more of a hand drawn effect.
below is my script and the result im getting from it now
thank you
