The Humble Coffee Mug

For beginners, after I run through the basics of color wheels and value scales etc.  I like to do a coffee mug, something close to home!  The elipses, the reflections, the neutrals and gray scales are all there.  The rich coffee color can be more colorful than people realize.  Here is a demo I recently did too illustrate that point.

Of course the sketch can be a good start.  I have another approach with out the sketch but this can be scary for beginners.
