WayneTully1 teaches you how to draw a severed hand. Use a white piece of A4 paper and a mechanical pencil. Start with the wrist and work your way up to the index finger. Go down and draw the other fingers, paying more attention to the thumb. It needs to be in a right position to look realistic. When you're happy with your sketch you can use the pencil again, applying more pressure this time. Once you're done, you need to add details like curves, hair and fingernails. Also, because this is a severed hand, you need to make it look like the hand has been cut off from the wrist.
