Watercolor barn - I worked on the trees on the left.  I used 'dotted' color to make it look like clumps of leaves and worked to make the 'sky holes' more natural looking.  The colors I used were sap green, indigo, and permanent alizarin.  I then worked on the barn with sienna brown, some permanent alizarin, and some new gamboge as well as cobalt on the roof (a little bit).
