I recently took a Creature and Character Anatomy workshop with Anatomy Tools. The class was taught by Andrew Cawrse and Damon Bard. I created some thumbnails of a character I have had on my mind and Andrew and Damon more then helped me bring my character to life. The workshop was incredibly helpful and I highly recommend any of the workshops they teach. It will bring your anatomy to an entirely new level. Thanks for looking!
