In regards to your work not being limited to what was assigned, you should only be doing what is explicitly assigned. I go into this in more detail in the updated Lesson 0 video that goes over how to get the most out of this exercise, but to summarize, if you allow yourself to have false starts, then you're also giving yourself more reason to simply not take as much time as you need for each construction. Since, after all, you're allowing yourself to throw attempts away and start over.

In regards to your organic intersections, your work is generally coming along well, I have just two points to call out:

• Always try and draw your forms such that they are as simple in their silhouette as they reasonably can be. Avoid additional complexity, like these inward curves we see here on your third page.

• When it comes to line weight, remember that it should not be used to generally or arbitrarily reinforce the silhouettes of your forms. Instead, it should be used to clarify how different forms overlap one another, and in a fashion that is limited to the localized areas where those overlaps occur, as shown here. Again, this was primarily present in your third page - the first two were much better in that regard.

Continuing onto your animal constructions, by and large these are much better. There is still definitely room for improvement on the way in which your additional masses' silhouettes are designed (they still tend to be somewhat blobby, like this one here) but they're definitely improving as well, and in general you are demonstrating strong overall spatial reasoning skills.

Just be sure to periodically revisit my prior feedback - especially what I shared in terms of the design of your additional masses - as you continue to practice these concepts in the future. Also, I would recommend not including any contour lines on your additional masses, as they're not actually contributing anything to their individual solidity. It seems like you may be doing this just as a matter of course, as memorized behaviour, rather than considering what those additional marks are contributing to the construction. As always, you should be considering this about all the marks you draw, during the planning phase of the ghosting method.

I'll go ahead and mark this lesson as complete.
