Architecture

Painting architectural subjects can be quite daunting.  The tendency is to try to put in every detail.  The result is often a texturally overloaded rendering.  

In this painting of the St. Louis Basilica Cathedral in St. Louis, as usual, I tried to depict the major shapes: half circles, rectangles, and triangles.  I did NOT try to fill in every window.  A simple downward flick of the brush suggested the windows, and quick dabs and short strokes gave the illusion of decorative features on the façade of the building.  

If your goal is to produce an architectural illustration, maybe you should include all the exact details.  However, if your aim is to paint the architectural subject, reduce the number of details and merely suggest the ones you do include.  The result will be much more satisfying.
