Hi, great job on finishing Lesson 1! I'll be critiquing your work.

Lines

On Ghosted Lines and Ghosted Planes, your lines tend to wobble which may indicate you aren't drawing from your shoulder or simply not drawing confidently. But, this is something you'll get more practice with in future lessons so make sure to keep practicing. Also, try not to undershoot your lines as it's fine right now but not a habit you want to make in future lessons.

Ellipses

On Tables of Ellipses, your ellipses are slightly wobbly and not all, but few of your ellipses are drawn through more than 2 or 3 times.

On Ellipses in Planes, the same mistake of your mistakes being drawn through more than 2 or 3 times is visible here. Some of your ellipses also aren't touching all 4 sides or extending outside of the plane itself.

On Funnels, you did exceptionally well asides from the drawn through multiple more than 2 or 3 times. The minor problem is that some of your funnels aren't properly aligned with the minor axis, causing your ellipses to be unaligned and look uneven. Some of the ellipses at the end of your funnels also tend to be a little loose than the ones inside.

Boxes

On Rough perspective, your lines are wobbling a lot which may because this is the first time drawing boxes without a ruler and instead utilizing the ghosting method. https://drawabox.com/lesson/1/10/wobbling

On Rotated boxes, wobbly lines are present here and some boxes are sticking out more than attended. I may be wrong, but I some lights are reattempted to fix the ones that went wrong, it's alright to make a mistake and you should move on to the next line as if it was perfect.

On Organic perspective, you did a great job and there's less wobbliness on the lines.

Overall, you did great and definitely deserve to move on the 250 Box Challenge. The main problem you should focus on is your wobbly lines, which you'll definitely get more practice in with the challenge. I also suggest, this isn't necessary, to warm up by spending at least 10 - 15 minutes of your time drawing Ghosted Lines to get more practice in. I also urge you to apply lineweight and hatching when drawing your boxes as it'll make them look more solidified and better. Keep up the great work! :D
