I never really do unless the line is so long/big that I can't make a decent one with me hand. XD; Otherwise I prefer to draw it myself, that way I can change the line weight as I go. But for this style is works well. I've done 3 images like this now, and I love it. I've never been this fast. XD I'm keeping this one. Kinda nice having 3 styles to choose from now.
True. Which is why I always add color to my lineart and don't keep them black. I actually often sketch in a dark blue/grey-ish color, it's really nice for some reason.
