Light & Shadow

I painted with acrylics yesterday for the first time ever.  Compared to watercolour -- which is all I know -- acrylics were novel and freeing.  Being able to add paint on top of paint and not make mud is great.  Otherwise I have everything to learn.  For the first day we painted a still life of white objects using two colours only -- white and umber.  First we mixed three middle tones.  Next we painted the composition in outline with the middle tone.  Then all the shadows with the same tone.  Then every area that was left in the lighter tone.  Then we could add darks and highlights.  We also learned about 3 vertical and 3 horizontal lines in a composition.  Where the middle lines meet is supposed to be the focal point.

This is my first acrylic painting.
