I have written before that mostly I do the different stages of the drawing of Splinters in groups of pages. After that I have done the sketching part of some 40 pages, I start putting the linework in black. For this story I don't use ink, but black conté-pencil. This gives the line-art a more rough and irregular look, that fits more to the character of Splinters than a slick, smooth line.
It is a very detailed kind of work, especially for the small parts of an image. Because the pencils I use are very soft, I have to do a lot of sharpening. I think the store where I buy my art-supplies is quite happy with me... I use a lot of those conté-pencils.
The paper that I use is not smooth, in fact it's watercolour-paper with a nice structure, to give the line-work even more character.
