Hi Iceteacitron! I'm Starr, and I'm here to provide you some feedback.

Lines:

Lines start off wobbly, but they do improve a bit throughout the lines exercises.

You do a good job at starting at the same point on your superimposed lines and making your ghosted lines hit their initial target points. Meaning, you're doing a great job at thinking about and preparing for your lines! It looks like you mainly struggle with undershooting and missing your second points slightly, but you do seem to improve a bit on these through your exercises. And this will improve more as you continue to practice.

Ellipses:

You did a nice job on these exercises. You consistently drew through your ellipses 2-3 times and your funnels are split relatively evenly by the minor axis. However, many of your ellipses are wobbly. While I do notice some smooth ellipses in your tables of ellipses, this is something that needs work. It also seems that you freehanded some of the curved lines of your funnels since some are wobbly. Don't try to freehand parts where it specifically states in the exercise to use a utensil (such as a ruler/straight-edge or rounded edge) to draw.

Boxes:

The main things I notice are that your lines are still a bit wobbly, and it looks like you try to correct some of your mistakes in your rotated boxes and organic perspective exercises. Though it may be tempting, don't try to correct any bad strokes. You have to move on to the next stroke even if you notice a mistake in your previous one. Another thing to note is that it looks like you did not draw the very back line on some of your boxes in plotted perspective. It gets tricky keeping track of your lines in the exercises/challenges, so keep in mind to double-check your work to make sure you don't miss anything.

Overall, you followed the lesson pretty well. The main thing I suggest for you to focus on is your stroke confidence. A lot of your lines/ellipses are wobbly, meaning you might draw your lines too slowly or you're not drawing from your shoulder. As you continue, make sure you prioritize making a quick, confident stroke, moving from the shoulder and not the wrist. Your line quality and accuracy will improve as you practice this.

Thank you for sharing your work! I struggle with sharing my work too, but it's the best way to improve. I hope to come across more of your work in the future!
