Here's a life drawing sketch I did for class. We tend to look at things through our eyes and the info then goes into our brain and then our brain tells us an interpretation of what we saw. We want to interpret what we see but also be able to see things as they are (before we analyze the heck out of it).
It was a fun class. I really enjoyed it. It was supposed to be a 5 minute pose but I'm pretty sure it was 7 minutes.
