STEP ONE
For a street scene such as this one, I start with a relatively simple but accurate drawing using a grid as a guide. I overlay a gridded, clear acrylic sheet onto the image on the laptop and can then draw lines along awnings or window sills on the screen etc. to find a vanishing point. I keep this point in mind through the whole painting process. Here I have made a few compositional alterations. I have dragged one car back to fill a space in the intersection and slightly overemphasised the size of the tram.
STEP TWO
I start to map in the darks using the #6 short flat. My dark mixes are Ultramarine
