Starting with your form intersections, you're doing a decent job here - the intersections themselves demonstrate a strong grasp of how they all relate to one another, although there are a few issues I want to draw attention to in terms of how you're approaching constructing some of these forms.

First and foremost, I noticed that there are a few places where your linework gets kind of haphazard - areas where you're going back over your marks a few times (correcting mistakes, or just outright piling on a bunch of strokes like in the bottom left of the first page). Every single mark you draw needs to still employ the ghosting method. We may be 6 lessons into the course, but the principles from the early stuff still applies without exception. One stroke per line, no correcting mistakes. If you want to add line weight, those also employ the ghosting method to ensure a confident execution.

Also, be sure to construct your cylinders and cones around central minor axis line. You did this sometimes, but were quite inconsistent in doing so.

Moving onto your object constructions, you started off a little uncertain in how you were going about tackling these challenges, but I feel that as you progressed through the set, your overall confidence increased considerably, and by the time you hit the barrel demo and onward, you were really nailing them down effectively.

What stands out most to me is the fact that you didn't skip any steps here - it's very easy to make logical leaps and skip a few steps, but this lesson (and all those that remain in the course) really demand that you go through each step right on the page - kind of like "showing your work" in a math problem. You did a great job with this, subdividing your structures as needed to pin down all of the measurements in specific terms, and avoiding the sense of looseness or arbitrariness as you moved from stage to stage.

Admittedly you did get a little derailed on the mug drawing - remember that areas filled with black should be reserved for cast shadow shapes. There are a few exceptions we use sparingly (like conveying rounded edges in the speaker demo, which you used effectively on that plug), but in general you should not be using really thick line weight in any situation (it should be kept subtle, and be focused on areas where forms overlap one another), and should not be worrying about form shading in this course.

I don't think you necessarily need this, but I figured sharing this demonstration I have of another kind of mug might be helpful all the same.

Now, there's one last issue I wanted to call out that is present in all of your drawings. In the section where I allowed students to use ballpoint pens and such, I stressed the importance of not switching to different kinds of pens to separate out your object from the construction lines. Reason being, I don't want students to fall into a situation where they have to trace back over lines that earlier phases of construction already established. Basically, I want students to altogether avoid the tendency towards a "clean-up" pass, as it encourages tracing and hesitant linework rather than focusing on confident executions. So, be sure to keep that in mind for the last couple parts of the course.

Anyway, I'll go ahead and mark this lesson as complete. Keep up the good work.
