I've been trying to learn how to achieve more organic drawing and shading styles in my illustrations. The attached drawing is a good example of what I'm trying to accomplish. Do you think this was done by hand? If not, how do you suppose the artist achieved this style in Illustrator? I've seen this style in a lot of digital illustrations. I've tried using grain texture on a black to white gradient but it always comes out looking very cookie cutter and digital.
This was almost certainly penciled in and inked with pen and marker. You can achieve that sort of stippling in Illustrator if you want - zoom in and use the 'Blob Brush' like you would a pen.
