Fridays Oil Painting ( figurative ) work in progress.

I'm attempting to work from a photograph, I prefer to work from life but I'm seduced by the idea of doing a series from a farm that I worked on (volunteered ) in exchange for photographing my friends business.
I'm finding it a challenge, since I don't have any sketches or color notations for the photos.
I did do a few in the field , the successful ones I sold.
Relying on my knowledge of painting from life, I noticed the photos just don't have the colors, I'm going to have to invent them.
