Evolution of a Mural

I painted this little boy's room a year and a half ago but the family moved a few months later and so wanted the same basic composition but with his name on a steam train rather than on a line of laundry since the young master - at the advanced age of 2& 1/2 - has an enduring love of that era of train.  (Thomas, you know).

Original sketch; didn't bother too much with the trees since, well, I've done them already.

One hour in, sketched in the composition and begin blocking in lights 'n darks.

Four or five hour mark; mostly blocked in with colour.  The Mom wanted the train in shades of blue rather like Thomas but less bright and more tasteful.  Tomorrow I'll continue to de-wonkify the backend of the train, paint on the letters and take a stab at depicting the actual railway.  I find I prefer to tackle the more difficult, finicky bits first to get them out. of. the. way.  Time permitting, I will fine tune the landscape elements. 
Day three will, hopefully, bring it to stupendous fruition!
