Guest post by "Being Useful" I think the colored lines thing can work fine(look at Disney!)
The main problem here is that the panel looks like a newspaper misprint--the colored lines and the fill colors don't match up. It makes it look very surreal.
I wouldn't abandon it completely, but I would consider doing some practice runs with it to get it how you want.
For the purposes of this segment, it works well--she looks about as insubstantial as she seems to feel running face-first into that pointed question.
