Hello NEHA18! Congratulations on finishing Lesson 1! I will critique your work, hope it will help.

I'll divide my comment into 3 sections.

Lines

Superimposed lines are mostly executed confidently. Overall they don't frail on both ends, they frail only on one, this is ok for now. But sometimes they frail on both ends, and this is a mistake. Please always make sure to spend enough time to place your starting point carefully. Second moment is that some of your lines arch a bit. Please draw every line from your shoulder and if you do but the problem still exist, try drawing an arch conciously in different direction.

Ghosting lines are fine, but sometimes they wobble at the very end. We should not worry to much about end point and instead prioritize confidence over accuracy.

Same goes for your planes:better to always concentrate on confidence, accuracy will come with practice.

Ellipses

In this section you did a really great job by executing ellipses confidently and drawing through them 2-3 times.

Ellipses in funnels is a very tough exercise and you nailed it well!

Boxes

Plotted perspective: some vertical lines are not parallel to each other, but overall ok.

Rough perspective:

Width lines must be parallel and height lines must be perpendicular to horizon because we assumed that. We draw in 1 point perspective to simplify the exercise. Without that we would need two more vanishing points for these lines. You'll practice it in 250 box challenge. But why you didn't continue some lines to horizon? It is a crucial point in this exercise. You should do this and check how far they are from VP. Also you should use ghosting method before so that your lines will be more accurate and confident.

Rotated boxes are very good. You kept them close and tried to draw through then.

Organic perspective.

Solid work! Nice variety of sizes and rotations.

Overall you have a great start! I hope this critique wasn't to harsh and will help you to improve even more.
