I put a lot of emphasis on abstract design in my work, even though it might seem to be a representational painting. An abstract design is much more interesting if it incorporates points, lines, and massed shapes in its design. I often use brushwork expressively to represent different objects in a shorthand way. If you do this effectively, you can incorporate the point, line and mass shapes into your compositions just by using brushwork, and so make your painting much more interesting to look at.
If your painting has calligraphic (like script handwriting) shapes in the middle of large mass shapes, paint the mass shape first thinly and then superimpose the calligraphic shapes using a small brush and an impasto stroke.
