I attempted something similar but with a different pose. Applied, or tried to, what Patrick suggests throughout his drawing. Anatomy is still a learning point for me and having better control over the values as well.

The third long pose complete, really happy with the finish on this one, my best yet so far I believe of the long pose series. The pattern I've come to notice, is that the beginning/construction of the drawing is what I'm finding to be the hardest and slowest points of my drawing process as compared to the render. I feel that my artistic insecurities and/or incompetence is most revealed in the beginning stages, the start always feels like a gamble for me and one where the odds aren't stacked in my favor. Once again the fear of failure is prevalent throughout these lessons and even more so outside of them in my own works. I hope that with mileage this will lessen and I'll be able to go into artworks with less fear, less worry and more joy. I'm trying to love all stages of the drawing as you suggest we do, a task that is easier said than done for me hahaha, construction is a great weakness of mine always has been. The end result of these lessons have showed me what I could achieve in my own works once I no longer have to battle so hard with the initial stages of a drawing. This is the great thing about these lessons, even in our losses/struggles we can gain a victory in the sense that it indicates our own artistic weaknesses, and reveal to us what needs working on, cheers!
