Painting a landscape in acrylics - part 2

At this stage of the painting, I am blocking in some of the darker tones, and beginning to construct the various buildings. I am using stiffer pigment and building up the texture of the painting. I do this in different ways. I may stipple with a stiff hogs hair brush or sponge, use a palette knife, or print materials down. There are lots of different mediums that can also assist in this process.
e.g. sand texture gel, glass beads texture gel, heavy structure gel.
