“We need our lines to vary in what is known as “weight.” “Weight” of a line basically means how thick or thin your lines are. A lot of weight is thick a little weight is thin. Making your lines vary in weight adds a LOT of character (makes them look cool.)”
It’s a lot of reading but SO worth it. Lots of great graphics in the middle to explain line weights and such.

But the process seems so long, much easier to scan in a complete painting?
Scanning in a painting gives you a raster image - which is non-scalable in any effective degree. This is a way to create a completely digital image that is in vector format, thereby able to scale from the head of a pin to the side of a blimp without any loss in quality.
Trust me, it’s worth the time taken!
