Sketch group

I went to the open sketch group this week with a live model.  I spent about 45 minutes on this pose and am pretty pleased with the results! At first the hair was difficult and I kept reminding myself to look for masses of shapes which makes it easier to simplify the form.  If you click on the image to see the full size drawing, you can see I made some color notes at the top.  The lighting was just perfect and the model was sitting on these brilliant colored cushions and fabrics so I'm planning on working this into a full size painting.  Now the only question is, pastel or watercolor? I'm leaning towards doing a small color study in pastel (9x12) and then doing a full size watercolor (18x24).  Thoughts? I rarely paint nudes so it would be a venture into the unknown for me...
