After reading a few posts, I decided I needed to stop lurking and start showing my humble sketches.
Since I haven't drawing since High School (over twenty years), and only recently decided I needed to be more creative. I picked up Keys to Drawing by Dodson and dove into the exercises.
Update: Now (January 2013), I realizes I need to focus on developing my observational skills (the basics) before working on anatomy. It doesn't seem as fun or sexy but without it, I'm doomed to be poor or worse yet "mediocre." My game plan is to study Deborah Rockman's "Drawing Essentials" and after some "Lessons in Classical Drawing" by Juliette Aristides.
