Hello CrimsonVengeance, I'm ThatOneMushroomGuy and I'll be the TA handling your critique today.

Arrows

Starting with your arrows your linework is looking confident and well executed, with only some small signs of hesitation present, smooth linework is very important for arrows as it helps communicate the sense of fluidity these objects have as they move through the world.

Your application of hatching is looking pretty decent as you execute it with parallel and confident lines, it's also placed at the correct side of the bends which helps differentiate between the arrow's segments. However don't forget to [always make use of extra lineweight on top of the overlaps(https://drawabox.com/lesson/2/4/step4) after finishing your arrow in order to reinforce the depth of your arrows and add to their tridimensionality.

The way you can improve in this exercise further is to start getting out of your comfort zone more, while your arrows clearly look tridimensional, they have very similar rates of foreshortening and look very similar in their orientation and placement, so push the size difference between your arrow segments further, make it more drastic and noticeable, and consider that since arrows are very flexible objects that they can move freely across the world in all sorts of manners, so push yourself and explore the different possibilities of bends, twists and overlaps in order to challenge yourself and develop your sense of spatial reasoning further.

Leaves

Moving onto your leaves the fluidity present in your arrows is flowing quite nicely into these new structures and they feel pretty energetic, however something that jumps out to me straight away is that most of your leaves aren't folding in any way. As explained in the intro to this exercise leaves are objects which are very easily influenced by outside forces such as the wind or gravity, so when approaching this exercise, think of the forces that push through these leaves, and draw them with an awareness for how they flow through space from moment to moment, not only how they sit statically within space.

This is incredibly important because when tackling actual plant structures you'll find that it's very rare that all the leaves in your reference will be completely rotated towards the viewer with no folds or overlaps, so it's very useful to start tackling these kinds of leaf orientations as early as you can, otherwise they start to feel like flat stickers, glued to your page, instead of the tridimensional and free-flowing objects that they are.

Your application of edge detail is looking good for the most part, but you have a tendency to draw it with a thicker lineweight than your initial construction, be sure to keep the line thickness for each phase of construction roughly consistent, as drawing initial phases of construction more faintly can encourage us to think in terms of doing a sketch and later "cleaning it up", but in Drawabox exercises all marks should be given the same amount of importance, as we cannot clean up our drawings because we draw in ink, all marks count. You also have a tendency to cut back into your initial structure when it's not necessary, as explained here you should avoid cutting into your constructions whenever possible, instead adding new forms on top of it.

For both of these leaf structures you're skipping construction steps, this is because you're not following the complex leaf construction method for the top structure since you don't establish each individual arm of the leaf with the leaf construction method, by attempting to capture these complex forms immediately you create a less solid, less specific construction, despite how many arms there may be in the structure, they still exist as part of a larger structure and all influence one another, as such they should be constructed with the overall structure being kept in mind. This also causes you to zigzag your edge detail which is a mistake.

For the bottom structure you're skipping construction steps by not starting your leaf structures with the flow line.

Branches

For your branches they're generally coming along decently as you're making use of the exercise's instructions, which helps you maintain tighter control over your lines and maintain the solidity of your form. But while it's good to see that you're generally extending your line segments you're not always extending it completely up to the halfway point between ellipses, and sometimes you also draw segments in a single stroke which is a mistake as it effectively removes the overlaps we seek to achieve in this lesson and makes it easier for you to lose control over your lines.

So remember the instructions for this exercise: first we'll be starting our initial segment at the first ellipse mark, then extend it past the second ellipse and make sure that we're extending it fully up to the halfway point between the second and third ellipse before stopping our line. Afterwards we'll start our next segment back at the second ellipse and extend our line from there, continuing this pattern until our branch is finished.

It's good to see that for your ellipses you're drawing through them twice, this helps maintain their fluidity and confidence. Still on the topic of ellipses it's good to see that you're aware of the ellipse degree shift, , but some of your ellipses look too consistent sometimes which flattens your forms, so don't forget that as a cylindrical forms shifts away or towards the viewer that the degrees of it's ellipses will also shift.

Plant Construction Section

Now let's analyze your plant constructions.

One thing that jumps out to me straight away is the fact that you're grinding, as well as the fact that you didn't pay attention to the instructions for the homework assignments as closely as you should have. In the Homework section of the lesson it's clarified that you should submit 8 plant construction pages and that while you're allowed to submit your attempts at the demos alongside your homework, that they should make up less than half of your submitted pages. You submitted 11 pages instead of 8, and only 1 of those pages is an original plant.

By tackling the same demo constructions over and over again you also limit the range of plants that you attempt in this lesson and thus, limit the challenges that you encounter when drawing which gives you less room for growth as you spend more time trying to perfect a specific plant, instead of developing your sense of spatial reasoning by experimenting with different types of structure, which would force your brain to truly understand how the objects you draw exist in tridimensional space, and not just attempt to copy how a specific plant looks.

For your attempts at the demos you're also often skipping the last step of these demonstrations - the texture. Not following through with the detail in the demos means that you miss out on an important part of developing your work and your understanding of 3D space as even though this course tackles two concepts - construction and texture, they both focus on the same concept. With construction we're communicating to the viewer what they need to know to understand how they might manipulate this object with their hands, were it in front of them. With texture, we're communicating to the viewer what they need to know to understand what it'd feel like to run their fingers over the object's various surfaces. Both of these focus on communicating three dimensional information.

I've also noticed this note at the top of one of your pages. As explained back in Lesson 0 students have but one responsibility - to give themselves enough time to apply the lesson material and follow the instructions to the best of their current ability.

Multitasking, splitting your attention, or doing any other set of things that can distract you while going through the lesson material means that you won't be getting out as much as you could from each individual exercise because your focus is diminished and thus - the amount of information that you absorb is also diminished, it can also make it more difficult to evaluate your homework assignment. You learn more when you're fully focusing on the task at hand, so try not to mix leisure time with study sessions.

For the most part as you draw stems and other branch like structures in your pages you're still committing the same mistakes from before, not trying to extend your lines far enough, or trying to draw certain edges in a single stroke.

Your mushroom constructions are moving in the right direction, although you might find it easier to keep their several ellipses aligned to each other by starting your construction with a minor axis.

Many of your pages feel unfinished as they have enough white space where you could have added another construction - or better yet, you could have started your constructions bigger, this would have allowed you much more space to fully explore the forms of your plant structures and give yourself as much space as possible in order to fully engage your shoulder when drawing. Your potato plant construction also feels unfinished because you didn't draw all the leaf structures present in the structure, leaving a couple of gaps there.

For this construction you skip some construction steps by not always using the leaf construction method for the petals, and you also leave some arbitrary gaps between your leaf's flow line and the outer edges, avoid this as much as you can, these two parts of the leaf structure should connect in order to ensure specific relationships between each phase of construction.

Final Thoughts

While you are moving in the right direction with your constructions, the variety of work you have shown is too little in order to accurately evaluate your homework. It's also difficult to gauge whether you have understood the purpose and instructions presented in the lesson material because you haven't applied it to your own work.

As such I'm going to be asking you for some revisions, please look over the relevant lesson material and reply with your work once you're finished.
