For my portrait exercise I obviously used blue and orange.  I tried this one a couple of times.  It seemed the more I tried to paint the worse it turned out, so it looks like I stopped painting too soon, but it definitely looks better than the one I spent a lot of time on.  The monochromatic color scheme is a little rough, but I just started dark and kept adding white to the blue.  For my split complementary exercise I used blue violet, blue green and yellow orange.  By the time I got to the Triadic exercise I was getting a little tired and not sure I created too interesting of a design.  I call it “Tidal Wave.”
