I thought it might be interesting to post a stage by stage painting. So here is Wilbur - the drawing from Summer School.
The background washes were an ultramarine blue for the sky and yellow ochre for the sunlit clouds.
This wasn't what was in the photo at all, but that's an artist for you! We like to change things that aren't necessarily attractive into something that is. ( I hope it is!) Artistic license, its called. Wibur's owners will hopefully prefer it too.
