I am going to make some of clouds/sky series paintings and this is one of them.
On a canvas underpainted with a few layers of white and orchre, I made brief outlines with white paints,
So far, so good.
I have no idea what it will be at this point as usual. It may be like daytime sky or that of dusk.
I will just allow my brush as it goes, and use any color as I feel right.
After few layers, the painting usually start to set up a situation for itself.
Until that happens, I just have to repeat my image trial with some colors and compositions, and wait and see.
