Here are some lineart tips for those who have been asking how I do my lines and how I get them so smooth. I also recently browsed a friend of mines gallery and I'd really like to help them, problem is they really don't listen. Hopefully they see this. I've had this tut sitting around for a while now, I guess it's good to put up now.

I like it better than sai for lining, thought I still tend to use sai. The strokes just feel much better, and working at a bigger canvas is no problem, I also don't get that wild wisp problem that sai has when I get ready to color my lineart.
So there you go, if you have any questions, let me know!
One of the screenshots for the inking brush I had was old, just updated it. Sorry for the inconvenience!
