>>1556000>not really my best work there as far as line consistency goes but I don't really have anything else on hand to screenshot...While not perfect, it is consistent enough to give it a bit of "character" and not be uniform.
Here is a quickly version of how I would have done it to save a few more nodes - this isn't to show you up, but to show you a different perspective on things, and how to think about your lines and nodes.
The PURPLE lines show how the lines I made started out, the RED show the final result. I also screencapped the bezier levers so you can see how they work.
I could have been more precise in places overall, but I did this in less than five minutes, and wanted to keep a little bit of that character you put into the lines.
Hope this gives you some more insights that'll help you think of node placement...
