Hello Melos, 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. 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.

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, 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.

This structure is looser than it could be, because you skipped construction steps and tried to capture the complex form of the structure right away, instead of constructing each individual arm with the leaf construction method and only then connecting them together. Even though leaves are single entities they can still made be made up of several parts.

When it comes to your addition of edge detail in some of your constructions you need to spend more time with the execution of each mark - because there are so many and they seem individually unimportant, you're putting less time into each one and so they do not properly rise off and return to the existing stroke - there are often gaps, overshoots, and zigzagging marks which is a mistake that could be avoided by putting more time into the work. No mark you draw is unimportant - if you decided it was worth adding, it's worth giving as much time as it needs to be done to the best of your current ability.

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.

There are a lot of visible tails present in these branch structures, while this is a very common mistake we can attempt to mitigate it by limiting the amount of ellipses in our branches, by spacing them further apart we'll allow for a bigger length of runway between ellipses, and ensure a smoother, more seamless transition between marks.

For ellipses it's good to see that you're making an attempt to always draw through them twice, as that allows for a smoother mark overall. 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 now let's take a look at your plant constructions, which are generally coming along well made, as you're following the construction methods and techniques introduced in the lesson which allows you to construct really solid looking and believably tridimensional structures. I can see a good developing sense of spatial reasoning in these pages.

This is all very good and it's helping you develop a strong sense of spatial reasoning, there are only a couple of small things that if kept in mind will help you take your work to the next level.

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. Going further don't forget to construct the outer rim that's present in most types of plant pots.

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.

It's good to see that you're drawing through all of your forms in your work, as that allows you to work through the tridimensional puzzles that arise as we tackle these constructions. It forces you to think not only of how these structures look, but how they exist in space, how each different form connects with one another.

Final Thoughts

In general your work is good, you're starting to understand the purpose of these techniques and exercises and making use of them in your work, if you iron out on a couple of issues you'll be on the path towards drawing even more solid and believable tridimensional structures.

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