Congratulations on having toughed it out!

-Superimposed Lines-

Some of your lines have fraying on both ends, remember to take your time. You have total control over the starting point of every line that you draw, so as long as you're not rushing you'll always be capable of having your lines start exactly where you need them.

Some of your straight lines arch a little bit. If you're not drawing with your shoulder, you should be, it might feel awkward and physically tiring, but the more you do it the easier it will be in the future. If you are drawing with your shoulder and still arching like that, try to arch in the opposite direction as to make a straight mark.

-Ghosted Lines-

A few of your lines curve towards the end point in a few spots, remember that accuracy is not your first priority. Focus on making a smooth, straight and consistent line. Then, you can focus on hitting the mark, again, with a confident, smooth line, even if you over or undershoot the mark. Finally, once you've got all that down, you can start nailing the point accurately, and confidently.

I see that you've attempted to draw a second line to correct or finish one that's missed or fallen short. You shouldn't feel the need to correct for any mistakes. Nobody nails it on their first try.

-Ghosted Planes-

I can already see a lot of your linework has improved by this point!

However, I see a lot of wobbling in several lines. Remember, it's okay and expected for your lines to be inaccurate. Carefully ghost your lines two or three times, and repeat let muscle memory take over, you'll miss the mark plenty of times, and that's okay. You'll start to nail these down the line.

I see a few lines you've gone over more then once. There's no need to do this, continue as if each mistake was correct.

-Ellipses-

I'll condense all this into a single section

Remember to draw confidently and draw over your circle 2-3 times. It's more important to achieve a smooth elliptical shape then accurately draw within bounds.

Your minor axis for the funnels should ideally bisect your ellipses down the middle. You've done a good job on most of them, but a few are quite off, an a few have more then one axis, which they shouldn't.

-Perspective and Boxes-

I don't have much to say about rough and plotted perspective. It will simply take time and practice to accurately line up with any vanishing point, particularly with rough perspective. Take your time and always put as much thought and your best foot forward to line up with the VP whenever your try.

Rotated boxes is the heavy hitter of Lesson one. You did good just toughing this one out. Just keep in mind, that you can line up each box with the ones next to it, you can take a lot of information from just those boxes you've already drawn. Regardless, solid effort, this ones hard.
