Nice work! You start out with a really nice showing with your form intersections - you've got a lot of complex, crowded interactions between forms there within a pretty limited space, but you seem to be handling them quite well. I'm especially pleased to see how you've got your intersection line stopping sharply when it hits the edge of one of the forms, then starting anew with a new trajectory as it continues on. A lot of students tend to try and smooth that stuff out, so I'm glad you understand how that is meant to behave.

Overall, your everyday object constructions do come along quite nicely. You're very thorough with the amount of subdivision you apply throughout.

I can see however that with the barrel, your ellipses definitely got tricksy, and that caused a bit of a fumble. I believe one of the problems here is actually the box in which you were constructing - you can see how the far ellipse ended up getting so wide that the width ended up being its largest dimension. This in turn threw off the alignment of the minor axis, since the minor axis is the narrower of the two axes. This appears to have been the case for your front face as well (the minor axis on that ellipse would be running more vertically). Ultimately the proportion of those box faces were more rectangular than square in perspective. It's not an uncommon issue, but it can definitely throw a wrench in things.

Moving onto your mouse, I did notice that you appear to have gone back over the "main" lines of your drawing with a different pen than you used for the underlying construction. This seems to be the case in a number of drawings, but it stands out a lot here. Remember that in the instructions, I mention that if you choose to use ballpoint, you should not be switching the kind of pen you use, and instead stick only to that one kind of pen (aside from filling shadow shapes). Reason being, I don't want students tracing back over their linework - tracing causes all kinds of problems due to how it makes us focus on our lines as they exist on the page in two dimensions, rather than as edges in 3D space. It'll cause us to draw more slowly (causing wobbly lines and garbled messes like the bottom left of your mouse drawing), and will also cause us to put marks down that reinforce the drawing as a flat series of marks rather than a solid 3D object.

Skipping down to your oven/range, you did a good job with the construction, but there are a number of issues in terms of how and where you're filling things in with black. First off, don't mix hatching with solid black, pick one or the other. Secondly, don't fill things in that have a local colour of black - we don't behave differently for any other coloured surfaces, so there's no logical reason that black should get special treatment. Instead, treat your objects as though they're all of a flat white colour. Focus your black shapes only to capture the shadows our forms cast upon one another. Lastly, on the feet of the oven you appear to have attempted to add some form-shading, which is different from cast shadows as explained here.

I really loved your waffle press - I felt the linework was really crisp and confident, and the forms were very solidly constructed. Pretty much everything from there onwards came out really solid and well built - your water jug still has a lot of scratchiness from going back over the lines in a haphazard fashion, but it still came out quite nicely too.

All in all, you're definitely doing a good job of applying the principles from the lessons, but you need to work on whatever is causing you to create those scratchy bits in your linework, as they really do take the quality down a few pegs. Other than that, keep up the good work. I'll go ahead and mark this lesson as complete.
