Thank you very much.Lately I bought a laptop with digital pen, so now I use that for drawing, because it's much faster.But this was done in vectors, that's how I did it until now. I used the "pen tool" to select the area I wanted to fill up with black and many areas like that formed the lineart. Of course my vector artsyle looks a lot better since I used it for more than 2 years, I still need a lot of practice with the pen to be as good with it as I was with the vector style
