The use of sketches, renderings and technical drawings to convey ideas about store interiors, shops, fixtures and presentations remains as important as ever today, as the approval process for any new project or design frequently involves more entities and players who can benefit from seeing a realistic depiction of the completed project.  I can develop renderings from sketches, blueprints or verbal or written descriptions, and they can be developed as simple line drawings or enhanced with pen & ink, colored pencil or markers.
