Thanks Jeroen - I like the Stratos - and the racing Mini's are good - they capture a nice sense of movement.
My problem with these sketches is that they hardly ever end up paintings - 1) due to time constraints but 2) (and more importantly) the paintings never look as good as the sketches.... which is frustrating, given the paintings take so much longer. I have a problem keeping the paintings loose.
The way I dod these sketches are overlays - I start with a couple of studies on normal Letter (A2) paper and then when I have a "base"drawing I like, I overlay it on tracing paper.This allows you to make small adjustments - for instance - in the "Doohan" piece, it took me a while to get the knee right - the original drawing had it "in" the shadow- I did several overlays and realized that it needed to raised above to give visual tension.
