Hello Henrietta0910, I'm ThatOneMushroomGuy and I'll be the TA handling your critique today.

Arrows

Starting with your arrows your lines are looking fairly confident and smooth, which helps communicate a nice sense of fluidity in your arrows as they move through the world. You're keeping foreshortening in mind while constructing your arrows which allows you to make really good use of perspective and the depth of your page, this gives a nice extra layer of tridimensionality to your arrows.

Your usage of hatching helps you establish how your arrows twist and turn in space and further your own understanding of the tridimensional space these objects occupy, as a finishing touch to your arrows don't forget to make use of added line weight on top of the overlaps to reinforce their depth.

In general you're doing well in this exercise, your arrows are looking fluid and tridimensional and there's a good variety in the rates of foreshortening and the way they twist and bend through space, so don't forget to keep tackling this exercise during your warm ups in order take your understanding of arrows and 3D space even further.

Leaves

The linework for your leaves is looking smooth which helps communicate their fluidity and sense of energy, it's good that you're not only trying to capture how these structures sit statically within space, but also how they move across it from moment to moment.

Your addition of edge detail is generally looking good, as you don't usually attempt to capture more than one piece of edge detail at a time, and you generally construct your edge detail additively. You're also keeping the line thickness between your phases of construction roughly consistent, all of which is very good and helps you create a tighter, more solid construction that still feels fluid and energetic.

Branches

Moving on to your branches they are coming along really decently made as you're generally following the instructions for the exercise, but they can still be improved. While it's good to see that you're drawing your edges in segments you're not always starting your new segment back at the previous ellipse point and superimposing it on top of the preexisting mark, you're starting your new segments close to where your previous mark ended, which partially removes the healthy overlaps we seek to achieve in these structures.

So remember how branches should be approached, by having your segment start at the first ellipse point, extending it past the second ellipse and fully up to the halfway point to the third ellipse, afterwards you'll start a new segment, making sure to place your pen at the second ellipse and repeat this pattern until your entire branch is complete.

Don't forget to always draw through your ellipses twice as this will create a smoother and more confident look in your marks. It's good to see that you're aware of the ellipse degree shift and making use of it in your constructions, which helps these structures feel more solid and believably tridimensional.

Plant Construction Section

And lastly let’s take a look at your plant constructions, which are coming along really well. You’re following the construction methods from the lesson, and it’s clear that you're building solid, three-dimensional structures. Your spatial reasoning is improving nicely, which is fantastic.

You're on the right track, but there are a few things that are keeping you from reaching your full potential. So here are the points you should keep in mind whenever you tackle these exercises again so that you can continue to develop your skills.

Firstly, always keep in mind that the construction methods and techniques introduced in this course must always be applied to your work, as they're tools which will help you construct much tighter and solid looking structures, there are times where you deviate from the construction methods by not starting your branches with a minor axis. Remember that they're not guidelines or suggestions - they are rules.

When approaching cylindrical structures such as mushrooms starting with a minor axis will help you keep your several ellipses aligned to each other more easily.

You're not making use of edge detail in your pages, edge detail would have greatly helped you further communicate the form of your structures and how they move through space, but by not adding it they're left very simple, so make sure to add edge detail whenever possible, and remember that only the last step of leaf construction - texture - is optional.

Make sure to keep all stages of your construction tight and specific, don't leave gaps in between stages of construction, such as a leaf's flow of line and it's outer edges, they must connect.

In your attempt at the potato plant demo there are a couple of deviations from the instructions for the demo which stopped you from getting the most out of the exercise. In the actual potato demo the part that's filled in with black is basically so densely packed that the shadows fill up the dirt you can see between the gaps - but in your work you've filled it in with generic hatching. So make sure to follow the demos more closely.

Final Thoughts

In general you are doing well and your work is looking good, you're starting to understand the purpose of these techniques and exercises and making use of them in your work effectively, as such you demonstrate that your sense of spatial reasoning is developing really nicely.

I'm going to be marking this lesson as complete. Good luck in Lesson 4.
