This shows my work over the weekend, three full days and nights! Just for your reference, I did not use anything to save my whites, like in the grass or flowers or the highlights in her hair. I painted around the parts I planned to save. Also I do not use white paint, all highlights are the white of the paper showing through!
The grass is finished but I will probably smooth it out near the end. I am starting off with the under washes to her pants.
Here I smoothed out the upper sidewalk and have gone deeper into the pink pants. Also started shadows on her shirt.
More to the shirt.
Almost there. A few more hours to just tie it all together.
