Hello again,

I'm glad that you appreciated my critique and willing to work on it. Also, you've uploaded the missing pages as requested. I've gone through them.

There's no doubt your line work is pretty good and well done. Lines are consistent and show confidence. But your Organic Perspective or the Boxes need some improvements. You will have to start thinking that how a box or any object sits in the space. While drawing through boxes in Rough Perspective, you've done good job and those boxes nearly seems to be in a 3D space. As in the Organic Perspective, because of not allowing to draw through the boxes, you couldn't visualize those boxes in 3D space properly, though few of those look pretty good.

So, always keep practicing and visualizing the objects in 3D space. Don't forget to draw using your shoulder. Keep warming up with some of these exercises like Ellipse in Ghosted Planes and Organic Perspective or simply Boxes, before you do any of the exercises or work, it'll generate a drawing memory and help you to achieve whatever you're willing to draw without struggling to figure out the right marks.

And now it's time to move on to the 250 Box Challenge, where you'll get to practice the boxes ultimately, so no need to worry about whatever mistakes you've done in these past Exercises. Just move on and always appreciate & enjoy whatever yo do. Don't feel pressurized or rush to complete the exercises. Look at it as your favorite job and get lost into it, enjoy it.

I hope you'll improve and mold your skills in an Artistic Way.

All the very Best !!!
