I've looked through your profile and noticed you went to Lesson 4 before receiving critique on this lesson as explained in the instructions in Lesson 0. Although it's not a strict requirement for free users, it's still advised against doing this as you won't get as much out of this course. Despite that, I will critique your work here and the next lesson as if they had been critiqued prior to moving onto the next lesson.

Starting with your arrows, you're doing a great job here, drawing them as if they flow confidently and fluidly through space. This carries over in some of your leaves, but I did find that a few of them were just laid out as flat against the page, rather than really pushing through all three dimensions of space. This may have been a result of the reference choices, but in the future, feel free to construct your leaves to be more fluid and then look into your references when applying edge detail and when constructing complex leaf structures.

One thing about edge detail that I'd like to warn against is viewing it as if you were redrawing the entirety of the leaf in one go. Construction is about building upon the structure that is already in place, adding to it and defining the parts that change rather than replacing it entirely. Especially when you do so with a purposefully thicker line, it's going to diminish the overall effectiveness of the constructional principles as a whole.

In this leaf you drew, it appears as if though you skipped the constructional steps right off the bat. Instead, what you want to do is focus the idea on adding something physical, as shown in here and in this leaf demo.

I'm pleased to see that when applying leaf texture, you're doing so by thinking of these as a series of small tubes casting a shadow as demonstrated here in the leaf exercise instructions.

Moving onto your branches, these are largely looking quite good. You're keeping their widths nice and consistent with smooth confident lines. Although there are a few times where you're still not extending your segments fully halfway as explained here in the instructions. The additional extension helps the segments flow more seamlessly from one ellipse to the next and so on. Also, remember to go over your ellipses 2 full times before lifting your pen, but I'm glad to see you changing their widths to see how they move along the branch in space.

Continuing onto your plant constructions, I'm getting some mixed signals here. It appears as if though you're changing your approach with every plant you draw for no particular reason. I have some suggestions on how you can approach your drawings that I think can yield stronger overall results but also get more out of the exercises themselves. After all, these are just exercises. The goal of these isn't to get a pretty end result but rather on how we're manipulating forms in 3d space, building on top of one another, defining how they sit beyond the confines of a flat page.

As I said before, the thing that sticks out to me the most is how you approached your plants. In some cases, it even appears as if though you decided to take some alternate path, despite following the steps just fine earlier. An example of this can be seen here and in this flower. You definitely were aware of the instructions for applying edge detail but decided to skip the constructional steps and instead went about just drawing plants. Remember that the plants we're looking at are just a subject matter. We're not aiming to draw plants or even replicate what we see but rather to use our constructional knowledge and apply them to real life situations.

Also when you go about applying edge detail, remember not to zigzag as explained here. Add each and every mark one at a time carefully. Take your time with it.

Another issue is that you're not drawing each and every form in its entirety on some of these, opting instead to draw them insofar as they're visible. Most notably on this cactus you drew. As you can see from this cactus demo, you'll see that each form is drawn in its entirety. Remember that the purpose of these is to define how each form sits in space. They don't stop existing just because you don't see them.

On this last page, you started out your constructions very faintly, and then once you're more confident in what you're drawing, you go back in with darker lines. This isn't the approach you should be using here as it promotes the idea that those initial lines aren't actually there or that they aren't defining solid forms in the space in which you're working. But they do - every mark you make is a solid entity, and once it's there, it has to be dealt with.

Your daisy construction actually followed through much better as you drew each form purposefully and confidently.

Speaking of which, there's an arbitrary gap between the flow lines and the petal structure itself on the daisy demo you drew. Remember that every stage of construction provides an answer to a question, which must then be adhered throughout the construction. In the case of the flow line, it defines both how the petal moves through space, but also how long it's going to be. Once that's established, you must draw the petals such that they stop at the flow line's tip, in order to maintain a tight relationship between the different phases of construction.

Although this work calls for some revisions, I'll mark this as complete since you've already completed lesson 4. If you wish to receive feedback more quickly, go to the discord server and ask for it in the critique exchange channel. There, you'll be told to do 5 critiques and either Elodin or someone else will critique your work. Instead of waiting for months, this process should take a few days given your submission is at least 1 week old. Ultimately, it's entirely up to you.
