More work in progress photos. I’m struggling to get the clouds right. I need to try and get the detail and shading correct. Also when it’s finished the paintwork on the frames will be all crackled and flakey.

Looking closer, the greys are dark but not too dark, I may also bring a tiny bit of brown in and thin it down for the wood in the windows. Mostly it’s blending and shading to get a realistic effect.
