Foreshortening is a word used to describe the drawing of a person or object in perspective and this where I sometimes get myself into real trouble!
Let’s pretend we were to crouch and look at a person lying down on the beach. If we were to look at the person from the top of their head view we would hardly see anything of the side of them. So the motto with foreshortened drawings is, “the more we see of the end, the less we see of the sides.”
When tackling a foreshortened subject, I firstly try to establish whether the figure is lying diagonally and if so, which way is it sloping? To start on my page, I draw a very light diagonal line to guide me.
Finding the midpoint is particularly vital in foreshortened drawings and will appear not where you would guess it to be. I tend to treat the drawing as a jigsaw puzzle of many pieces joined together and return to my starting point with freehand drawing as often as I can. This way, my struggle with proportions becomes a little easier.
It is most important to draw what you see even if it doesn’t make sense. Having said that, this may not feel right as you are drawing because the shapes will be so different from what you know and recognize. In fact, the shapes could almost be described as nonsensical.
This rough charcoal foreshortened drawing below was so difficult to do and I think I must have unsuccessfully had at least six attempts. The mid-point is very deceiving here and appears just below the girl’s bikini top. After many attempts, I did the drawing while listening to an interesting topic on the radio. This is a good tip because it is enough to distract us so we lose concentration and allow the drawing to flow without trying too hard.

Edward A Burke’s drawing and painting site is also a great reference.
