I was on fire today! I've got another frame for my new project.
To sum up the project for those who don't want to read the post linked above, I'll be making 24 drawings of the same pose from different angles and then putting them together into an animation that gives the viewer a 360° view of the model.
Here's the Sixth Drawing
All Completed Frames Side by Side
When it became obvious that the lighting of the photos wasn't lining up nicely, I made a decision: Rather than painstakingly trying to match them all in Photoshop, I'll just reshoot all of the photos once I'm done drawing to ensure consistent lighting conditions.
