Certain types of illustrations, whether drawings or paintings, may need a little “extra” to add impact and/or movement to the subject matter.
In this instance I have used simple radiating lines and small circular shapes to indicate the speed and the action of this motorcyclist, the late and very great Northern Irish road-racer, Joey Dunlop. The lifted front wheel is one indicator that the rider is moving at great speed, but the addition of the dust and stones being thrown up by the rear wheel, adds to that sense of speed and indeed danger of this particular sport.
Do not be tempted though,
to overdo these indicators of speed, etc., as it may even obscure the movement of the actual subject or subjects.
