This sketch of a Soviet T-72 tank of the Cold War era was done with a 4B pencil. The cloud of dust behind it and the loss of detail in the lower wheel and track suggest movement. I'd already sketched one come directly towards me as I tried to capture the sense of atmosphere and a fast-turning tank, but in this view I wanted to bring in more detail as it moved broadside on from my viewpoint. The advantage here was that it paused enough for me to render a lot of the detail before it resumed a steady progress to the right.
Simply suggesting some of the wheels helped to give a sense of a moving vehicle and of course it made my task easier. To indicate greater speed I would normally lose more detail at the rear, but here I wanted to include detail I might need later. Spattering more muck around at the rear would also emphasise this effect.
Whilst you may not wish to sketch in the middle of tank manoeuvres these points can help when you are painting a scene with moving tractors in a field, or excavators digging up your local green space, and it makes quite a change from a still life after weeks of lockdown!
I will be doing a free 45-minute demo at 2pm on Tuesday 4th August which you are welcome to join in with your own painting at the same time - details are at https://www.shopkeeparty.com/
Both will be live online so you'll be able to ask questions.
Enjoy your painting.......
