So these are definitely a big improvement, and have made it considerably easier to point out your primary issues. Instead of writing out my critique here, I ended up doing most of it directly on your work with little examples and visual explanations to help you understand them better. You'll find it here.

Main points:

1. When constructing your animals' muzzles, you seem to create a larger form, then create another form whose relationship with the larger container are fairly loosely defined. Wherever possible, try and work additively - that is, adding forms on top of one another instead of cutting back into them. When you do have to add subtractively, it focuses on having strongly defined relationships between all the resulting forms. You can see a more specific breakdown of how I tackle head construction here. There is also a moose head construction above it.

2. You are overdoing your contour lines. It's not uncommon for students to just pile them on because they they're a technique they know how to use. You have to be thinking about what you're attempting to accomplish with each mark you put down however, and what that mark is going to contribute to the drawing. Applying techniques blindly will often causes us to add lines that serve no real purpose of their own.

3. Constructional drawing is all about moving from a simple structure and using that as a scaffolding for more complex structures that are built off of it. If you jump too complex too soon, without adequate structure to support it, then your construction will fall flat.

4. You still have a tendency to think more in terms of drawing lines on a page. Every single element you add to your drawing needs to be understood as an independent three dimensional form. Lines do not exist on their own, and so if those silhouettes are broken, the forms they're meant to define will not appear solid, and the construction upon which they're built will fall apart. You've definitely gotten better at drawing more purposefully, but you're still being quite timid in a number of areas, and need to work on that a fair bit.

Before I mark this lesson as complete, I'm going to ask you to do 4 more drawings applying the points I've raised here. I want you to do no more than one of these in a given day - this is to ensure that you don't attempt to get everything done at once. This also means I will expect you to submit no sooner than 4 days from now.

For these drawings, I've got two main restrictions:

• You will not be allowed to use any contour lines that sit on the surface of a single form. Contour lines that define the relationship between two separate forms are allowed (like the joint contour lines in the sauage technique).

• You will not be allowed to get into any texture or detail. Take constructed forms as far as they can go.
