Valley of the Rocks - stage 3

First colour pass on the sky - I couldn't get all of the sky done in one session as it covers too great an area so I left it like this for today as I didn't want to hurry it. Colours used were Prussian Blue, Phthalocyanine Blue, Permanent Orange, Unbleached Titanium, Lemon Yellow, Lead Tin Yellow Lemon and Zinc White.
