On
the upper part of the bushes, draw a few small horizontal lines, to
give the bushes the effect of movement, given that naturally the bushes
are moving and not all of them are the same.
In
this photo, I have drawn a few lines to divide and make some areas of
the hillside stand out.
With
the short bush, which we have previously drawn and smudged, we are going
to draw a few dark vertical lines so as to make some of the branches
of the bush stand out.
