Here I'm using a photograph of our lurcher, William (many of you will be familiar with this lad, since I draw him almost every day).
Step 1: Draw the basic 'shapes' first. Ignore detail.....
Step 2:
Having referred back to the photo, I saw that the head needed to move toward the viewer. I also added the football in his mouth.....
Step 3: Now is the point at which I put in some detail.
Note that the initial circles are still there, but I'm 'correcting' some angles.....
Step 4: With that done I can erase the unnecessary circles -
and I have my drawing.....
and Step 5: Add some watercolour -
plus in this case some 'action' lines to indicate movement.....
A simple enough exercise.
Recap: From all those circles, you will find the pathway to your
final drawing.
