I searched on here to see if it was discussed. But, I didn't find it, so here it is. The only question i have is what materials is he using? To me it looks like mixed media, charcoal and pencil? Also, I can't tell because of the grainy video but did he do a line drawing first? Because by the way he's going about the shading, it doesnt like someone who would do it one pass it looks like he already has a line drawing set.
