Constructing "Grandfather's NASH"

In the beginning there was a photo....

...originally B/W one, from the year 1954, where I added some colours with pencils. This car, American NASH, was owned by my grandfather (r.) and driven by him from Rautu, which was left to Soviet Union after World War II. - Two other persons are my father and me.

I printed the original photo on a A4 office paper with soft surface for adding some colours on it. Next step: a drawing of the view on a canvas (just an commercial ready-to-use one) with a pencil:

Some colours to check how they attach on the canvas.... (I like both drawing and painting of chimneys!).

The final steps usually take a lot of time. The night hours are really needed!

I finally make a decision: "This is all I can do". I could continue as long as I want but there will be a point of resignation: "Now I will finish my work". - I can still refine it later if needed, but at this very moment I feel that my work is done.
