I think you're definitely showing improvement over the course of the whole set, with the llama at the end demonstrating a lot of big strengths. There are however still some areas you're going to have to continue working at, so I've done a quick redline of your llama here.

Main points:

• The biggest and most common issue is that while you do a good job of thinking about how your forms wrap around the underlying structure along certain edges, there's usually at least one section that is left to sit loosely and not actually wrap around the underlying forms. Do what you can to think about how it wraps around throughout the entire additional form.

• Think more and more about how your additional forms can integrate with one another. On the head you did a good job of thinking of how the muzzle and eyesocket fit together as parts of a "3D puzzle" - we can do the same with some of our additional forms. Keep in mind that the additional masses are used to identify form structure that is usually made up of muscle groups, and those muscle groups all fit together with one another.

• Watch your eyeball - you have a tendency to draw it way too small, leaving you with limited capacity to actually wrap the eyelids around it. While the visible portion of the eye may be fairly small, the ball itself is definitely larger.

I also put together a new construction demonstration last night that may help as you continue to move forwards, you can see it here.

All in all, you're moving in the right direction and are showing a good deal of spatial awareness. As such, I'm going to go ahead and mark this lesson as complete.
