Whether you are in the process of design or at the stage of looking to get an idea of what view to show for a presentation rendering of it, an initial rough thumbnail, to a more highly resolved concept sketch (even with multiple views possibilities) can save time.  This can provide you with the beginning of developing the concept of what your design is all about. Even blocked out landscaping and terrain elements will help you visualize the eventual result.

The beachfront illustration below shows a resolved sketch of the proposed final view, followed by the completed watercolor rendering.
