Hello Shadowtheia, 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, but do remember that your hatching lines must still follow the principles of ghosting and mark-making, they must have clear end and start points, be carefully planned and executed and not end at arbitrary points. It's also good that you're making use of added line weight in order to reinforce the depth of your arrows, but don't forget that it must be added subtly to your work, only once, on top of the overlaps.

In general you're doing well, so keep tackling this exercise during your warm ups in order to take your understanding of arrows and 3D space further, experiment with the different ways arrows can twist and bend and move across space, try different rates of foreshortening and experiment with the negative space between overlaps, all of these will help you challenge yourself and develop your skills 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.

It's good to see that you've experimented with complex leaf structures but remember not to skip construction steps when approaching these more intricate structures.

These structures are looser than they could be, because you did not establish the spatial boundary that all of the later structures should abide to, despite complex structures being made up of several different parts, they still exist as a single entity, by not skipping construction steps you can ensure that your constructions are much more solid and specific.

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 keep the line thickness between your phases of construction roughly consistent, but don't forget to construct your edge detail additively as much as possible, that is, on top of your structure, avoid cutting back into the forms you've already drawn as that will cause us to focus too much on manipulating 2d shapes, rather than the 3d edges they represent.

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 extending said segment completely up to the halfway point between ellipses, 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.

For ellipses don't forget to always draw through them twice, drawing through them only once will cause them to be too loose and unconfident. When it comes to your application of the ellipse degree shift to your branches it can be improved, as it stands your degrees are too consistent and hardly change which is a mistake that flattens your structures. Remember that as a form shifts in relation to the viewer, so will the degree of the ellipses within that structure also shift.

Plant Construction Section

And lastly for your plant constructions you're doing really well. They're looking incredibly well done, you're capturing these structures in a way that conveys a great sense of tridimensionality and it's very clear that you have a great sense of spatial reasoning that you're demonstrating in these pages, good job!

There are only a couple of things you should keep in mind in order to continue taking your work to the next level.

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 or your branch-like structures with a minor axis. Remember that they're not guidelines or suggestions - they are rules.

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.

I've noticed that in some of your constructions you don't draw through some of your forms, such as leaves or branch like structures, this limits your ability to work through these tridimensional puzzles and limits how much you're getting out of the exercise. Not drawing through your forms means relying on your observation skills, instead of engaging your sense of spatial reasoning and truly trying to understand how the object you're drawing works, where it comes from, what it attaches to.

When approaching cylindrical structures such as plant pots make sure to start with a minor axis in order to keep your several ellipses aligned to each other more easily. It's good to see that you're going further and constructing the outer rim that's present in most types of plant pots.

Final Thoughts

I believe you've shown yourself to understand the concepts shown here and shown yourself to be capable of applying these methods to your work. Sometimes your work is not as good as it could be because you don't apply instructions as thoroughly as you should, so make sure to pay close attention to the instructions and take your time when going through these exercises.

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