Scaling up a Laugh

While finishing the 'Summer Market' painting (see previous post), I started a new painting possibly titled  'Laugh' . It is based on a charcoal drawing which I include below.  The foundation (washed out blue-red) layer was done in acrylics, on this I sketched the lines with charcoal pencil and now I have layed down a first layer in alkyd oils (dry in less than 24 hours).

The charcoal reference approx 16 x 14 cm

The painting  60 x 50 cm
