Portrait in Blue Shirt

OK I'm just getting started so bear with me. I plan to post my representational art. Some will be old....some will be current. I want to talk about what I like and hate about the work in an attempt to grow as an artist. Art , like life is complicated (which is why it is so much fun) so I hope to raise a lot of issues. I painted this portrait (11"x14" canvas panel) about a year ago. I love the shirt ...the economy of brush strokes on the dark gray-green ground worked well. I wish I could work this simply and effectively more often. The dark ground is dramatic but it shows thru a lot of paints lessening the intensity.
