Hello I'll be handling the critique for your lesson 3 homework.

Organic Arrows

-Starting by the organic arrows these are drawn with a good deal of confidence, which really helped you to convey a good sense of depth, you are also making some good attempts at the perspective of the ribbons, as it gets wider as it moves towards the viewer, and you are also aware of the negative space between the zigzagging sections of the arrow, however there are some instances where it looks a little bit inconsistent, so I want to quickly redirect you to this diagram , one thing that you can do is to actually draw your marks much slower, this is easier now that you have gained more mileage with the lesson 1 exercises, this will give you a better control of all the variables at play here. Lastly, your use of lineweight is good as you are limiting yourself to only applying it to the specific parts where an overlap happens instead of using it on particularly long marks.

Leaves

-Moving on to the leaves, the confidence with which you drew the arrows carried over to these, however you are making the mistake of zigzagging the edge detail, as explained here this result in a weaker relationship between each stage of the construction, and in general it is better to work additively, cutting into forms is much more difficult that adding forms. Your ability to cut into any given form will develop with time. Another important thing to point out is that when working with more complex leaf structures you are not following the construction method properly, take a look at this diagram, you can see that we are breaking everything into smaller and simpler steps rather than trying to capture a lot of things at once.

Branches

-Moving on to the branches they are moving in the right direction, your segments sometimes overshoot or undershoot so make sure to extend them fully halfway to the next ellipse. Make sure that each segment overlaps a good deal with the previous one, this will give you a better control of your strokes and will result in a smoother transition from dense to sparse.

You also need to keep working on the degree shifts of each ellipse, there are a few branches where it seems that the ellipses barely change degree, if you need a reminder you can reread the lesson one ellipses section.

Lastly, whenever forking branches try to stick to the method shown in the page, where you draw to ellipses close together, then draw a ball that fits those two ellipses tightly and then you can fork your branches, the important thing is that you don't skip steps

Plants

Moving on to your plants you are moving in the right direction and you are making good use of the construction method to break your subjects into their more simple elements, but let’s see what can be improved and worked upon.

-The first thing that I want to call out is that you tend to leave a lot of gaps between stages of construction, I am referring to the petals in specific. For example in this plant, there is a lot of gaps on each petal, keep in mind that each petal should end right at the tip of each flow lineThose empty spaces tend to remind the viewer that we are looking at a flat drawing. The same issue can be seen on the hibiscus demo, there are a few petals that do not connect correctly to the flow lines.

-The branches of the plants are not as well done as the ones on the actual branch exercise, you tend to draw your ellipses too small, in turn this forces you to draw them from your wrist instead of your shoulder. So try to draw those ellipses bigger, it doesn’t matter if your branches end up being the size of a trunk, we are not really worried about proportions now.

Also, whenever working with elliptical structures like pots, or even like the mushroom demo, try to draw a minor axis line to align them correctly,

-And lastly, I want to redirect your attention to the cotoneaster plant, I can see that you drew ellipses to block in the little berries, but then you proceeded to modify their silhouette as if they were flat shapes, given that they are forms with an actual volume we cannot use the same approach that we did for the leaves, instead we should add more forms with a fully enclosed silhouette and we should also wrap that silhouette around the initial form, this is a process that will be described in more detail later, but right now you can see an example here .

Okayyy, so that should be about it. You are already moving in the right direction in many ways, but I do want to see some of those issues addressed, so I’ll leave you some additional homework though it won’t be too much, I just want to see some of those issues addressed . Best of luck!!
