A ten minute and fifteen minute sketch I recently completed at a life drawing group a few weeks ago. Looking at them now I can see that the details are not correct, but not too bad. The leg lengths on the second sketch are definitely too short. You can see how I tried to extend them a bit. When you draw a figure it’s a good idea to work out where to place the head. If you are too low on the page you run the risk of losing the lower half of the figure as in the first, ten minute sketch. But these were swift sketches, drawn on pale brown Ingres paper which is suitable for the mid tones then drawn in black ink fine line pen and shaded with pencil crayons.
One thing I hate with life studies is when artists leave the head off. Especially when it’s a female study. To me, they may not be able to draw facial features, but by leaving the head off it makes the figure look more like a slab of meat, disturbing and disrespectful of the female model.
