Charcoal on paper. The approximate size is : 400 x 500 mm. I've been asked about the horisontal lines under my previous picture. In fact, i have a wooden surface, and while putting a paper down on it, i'm receiving such an effect of the horizontal lines.
It seems like this effect goes in accordance with that very image i'm trying to create with the help of charcoal, pastels, pencil or marker.
Here's an example of the charcoal portrait including an effect of horizontal lines.
