>>1734988>>1734983 here.Posting some progress. I realize, that some of the lines are too thick, so I will need to tweak it a bit.
I'm still not completely sure, where should I put anchor points. I guess it's best when they are used on the "strongest" point of a curve (the most consistent one, that isn't changing directions before or after the point), but I still have to move them around a lot to get better result.
