Our grandson, Brayden, had been over to our house for a visit. Before he left, I asked if he’d like me to draw his portrait. It took about ten minutes. This photo shows his reaction to it.You need to know that while I drew it, the view of his face was slighly higher than the photo of him here. The drawing shows his jawline, nose, and mouth at a little different angle than the photo of him,so I was looking up at his face when I drew it.
When I draw a face I first do a basic head shape, then put a line down the center where the nose goes. Next I find the line where the eyes appear, which is near the middle. Halfway between the eyes and the bottom of the chin is where the bottom of the nose goes, then halfway between there and the chin is where the bottom of the lip would be. I actually draw in the shapes of the shadows as well as the facial features.
I always have my sketchbook handy and draw anyone I can. It is a lot less expensive than hiring a model.
