From his presentation, we were able to get a picture of his design workflow.  The techniques that were used to translate a concept sketch over to a digitally painted rendering were so simple, yet fantastic.  However, a lot of the techniques relied on the software package.  One technique that he showed was using the tool set within Alias Studio.  There are tools that let you define curves to change a sketch’s proportion (stretch and pull) without destroying the image.  Unfortunately, this is not available outside of Alias Studio at this time.  Some of the other techniques were universal, like the use of brush presets.  David showed how to create a brush preset to easily place commonly used items within a rendering.  A simple example was that of a screw head and stitching.  It is a simple concept that is very easily implemented, but it can save a significant amount of time.  One of the other software pieces that he showed off was Mudbox.  It is basically a tool that is heavily used in the video game industry to sculpt characters.  David, however, showed how one could use it to digitally sculpt a product design.  With tools that are similar to physical clay sculpting, it is an intuitive way to digitally sculpt an object in 3D, while having a truly organic sense about the design.  It was extremely impressive to say the least.
