Mail Box - stage 2

A funny day yesterday, I just couldn't envisage in my mind what I was going to do with this picture and felt kind of catatonic so thank God I left it alone and resolved to start it today instead. Always a good idea to leave a painting alone if you don't know what you are doing!
 As usual over my breakfast coffee this morning I began to reconnect with what I wanted to do with "Mail Box" in terms of colour and lighting so I was able to get on with the first colour pass on the sky... except that once I had bashed in some colour I liked the orange against the blue and went with that instead! I was originally going to stick to the colours I used in my last painting....
Plenty of work left on the sky to get it right. The colours I used were: Phthalocyanine Turquoise, Ultramarine Blue, Ultramarine Violet, Permanent Orange, Prussian Blue, Warm Light Yellow and Zinc White - all Michael Harding paints.
