Back to basics drawing

I’m spending a whole week drawing, with 5 days of figure-focused classes.  Day 1 was proper old school instruction on what bits of skeletons matter and which major muscles I really should remember to look for.   Day 2 was more drawing muscles and general foreshortening, days 3-5  drawing a variety of models from life.     Fun and weirdly soothing, and I suspect ultimately very helpful.
