Good going on finishing Lesson 2! Giving everything a quick glance, I can tell I'm gonna mark this as complete :) but let's review it anyway to see if we got some good feedback.

Arrows:

You have a solid understanding on how to foreshorten your ribbons. Large in front, small in back. One thing you didn't quite get right is that this also goes for the spaces inbetween the arrows. That is to say, if you look at this curve, you'll see that in the back the curve is also much closer to eachother than at the front: https://drawabox.com/lesson/2/4/step1

All in all, no worries though. You put all the shading at the right spots too, you have a fine understanding of depth.

Sausages:

Your sausage shapes are well done. Especially your second page is smooth anf confident, doesn't taper, is nice and consistent in width. Very good!

The ellipses are less confident, they're rather wobbly and you didn't quite draw all of the ellipses through twice. I recommend spending more time on that for warmups! Something you also missed is to shift the degree of the ellipse. This is required to give the sausages the illusion of "bending", as it stands they are quite flat. Check out this bit: https://drawabox.com/lesson/2/5/ellipses

Textures:

You did decently well on the textures exercises. Be careful to not draw the shapes themselves, you have quite a few forms drawn out fully: https://drawabox.com/lesson/2/6/drawingforms

Be sure to imagine one strong light source, the point of the exercise is to only draw the strong shadows that come from that single point of light shining onto your object.

On most of your dissections you did it fine, but there's a significant amount of shapes where you either didn't transition from dense to sparse as you went around the shape: https://drawabox.com/lesson/2/6/notransition

or where you forgot to actually follow the curve of the sausages themselves: https://drawabox.com/lesson/2/7/curvature

You did break the silhouette properly everywhere, which is great!

Form Intersections:

You've drawn all your objects in roughly the same perspective, and kept all the shapes equilateral, both perfect! A solid amount of objects too, with plenty of overlap. The intersection lines are a bit awkward, but that is fully understandable and not the point of this exercise anyway.

However, your linework is sloppy. Lots of unconfident wobbly marks have been made, the hatching isn't spaced properly, there has been a clear lack of ghosting and just overall.. hastiness. It's not enough to make you redo this part, but please take it into account! Clean, confident linework is at the core of this entire course, and this really isn't done properly.

Organic Intersections:

Well.. there is a certain lack of creativity here. But honestly, otherwise well done. The shapes look proper, the shadows follow the curves of the object below it nicely, you have a good understanding of how shapes touch eachother in a three-dimension space and how to adjust shapes to give a good illusion of solidity. (there's one sausage in the middle somewhere that's really off, but we'll ignore that). All in all, you did this exercise well. Consider drawing another page where you don't just stack like a jenga tower but get a bit more creative like in the example homework: https://drawabox.com/lesson/2/9/example

Overall:

Awesome, you did great. Continue on to lesson 3.

However, do take extra care of your linework, the form intersections exercise wasn't well done. Consider really slowing down the pace you complete the lessons at, and pay more attention to the marks you place.
