Most ghost drawings are a sheet with two eyes. This one is the other kind: a tattered, shaded, reaching figure that looks like it has been haunting somewhere for a long time. It takes about fifteen minutes, and the drawing part is the easy half. The shading is what makes it.
The walkthrough follows Art Hub Plus on YouTube, shot straight down over the paper so every mark is visible. The sketch is simple shapes in light pencil. The drama comes from two gray markers, a black pencil for the shadows and a white pencil for the moonlight.
What you need
A pencil, two gray alcohol markers (one medium, one dark), a colourless blender marker, and black and white coloured pencils. Marker paper or heavier drawing paper stops the gray bleeding through. If you only have a pencil, you can do the whole thing in graphite; the steps are the same, you just shade instead of colouring.
Why it looks scary
Three decisions. The shoulders are uneven, so it looks like it is moving. The fingers are far too long. And the hem is torn to shreds. None of those take skill, and together they do more than any amount of careful shading.
The order matters
Sketch everything light first, then gray, then black, then white. Marker over dark pencil goes muddy, and white pencil only shows over a dark base, so the sequence runs from lightest material to darkest and back to white at the very end.
Where it goes wrong
The gray goes streaky. Lay each marker layer down quickly while it is wet. Hesitating between strokes leaves lines.
It looks flat. Not enough black. Press harder in the eye sockets and the opening down the centre than feels reasonable.
The highlights disappear. White pencil only works over the darkest gray. Put the highlights on last, and only on the top surfaces.
More Halloween drawing
For the friendlier end of the season, a jack-o'-lantern is three triangles and a grin and a bat is a silhouette you fill in black. The shading approach here, layers of gray then black then white, works on any dark subject once you have it in your hands. For the fundamentals underneath all of these, start with how to draw.
