I dont know because Im not into cartoons like that but logically this is the approach I would use.

Yes, these are good ideas, but I' not very good playing with levels at least in this case.
It doesn't seem to work because other area of the image seem to fall in the same threshold.
Cartoon edges are tricky, because you need your mask to cover the whole edge vs the 2 edges of the dark line. Else when you filter you can get an empty line.
There migth be something to do with a sequence of logical merge to isolate properly only the edges and real dark areas (like kids air, space, etc).
