>>1976540Echoing what Derpy said, most lines should be fills. Some things like weaponry, some armor, and other things like that look fine in strokes.
Here is an example from one the vectors I worked on (and sadly haven't finished yet...). The hair ornament thing, to me, looked like a solid metal object so I used strokes for most of it. The base was a stroke that I converted to a fill to give it that tapered look. But all the lines surrounding it are fills, like the hair, ribbon, and skin.
And when I do lines, I usually do three "passes" to get them consistent:
1. Use a stroke to make the outline of the line, placing nodes in pairs. At this point, I don't really care about width and consistency, just parity.
2. Make sure all the of nodes' handles are parallel. Still don't care about consistency here.
3. Once that's done, I try moving all the nodes to make the line consistent. I usually zoom in and out to compare the line to the surrounding lines. Then I fill it.
At the left of the picture you can see the end product of the line before I change it to a fill.
