Hello, today I will take care of correcting your homework for the Third lesson.

I will try to focus on what needs to be corrected, in addition to what is being done well.

Lines in General:

I set aside a space here, to mention that in some cases you perform chicken scatching, or so it seems.

Most of the time it is when applying line weight, so I will remind you that it should be applied with a single fluid and confident stroke.

You can also notice it in several of the plant drawings. I know it's hard to keep the lines flowing in curves like the one in these drawings, but you can practice it during your warm-ups.

Arrows:

These are generally fine. They look fluid, and the creases in each arrow were drawn correctly. The sense of depth is also well done.

Regarding the lineweight, you'll want to avoid applying it to the very far parts of the arrow to maintain the illusion of depth. Having less contrast in those far parts.

Leaves:

The leaves look very well drawn. They follow their base line of flow correctly and fold convincingly.

On the left leaf, which seems to have more structure, I will recommend that you draw each bulge of it outside the baseline, and that its stroke returns to the baseline, not inside it.

This maintains the main solidity of the sheet; when we cut it improperly on the inside, we are taking away its stability.

Of course there are some exceptions to the rule.

Please read more about this in this section on the error: https://drawabox.com/lesson/3/2/zigzag.

Branching:

The drawing of the minor axis and the ellipses aligned to it are fine; nothing to emphasize in that part.

Now, we have a problem with the flow of the branch lines.

Each stroke goes where it should, but they look very stiff. They don't join smoothly.

To correct this, try decreasing the line pressure before finalizing the line. And soften the pressure of the line that will go over it, as you start.

This is a bit difficult to explain with text alone, so please check the video of the exercise later: https://youtu.be/B42OHBTIIAY?t=170

Plant drawings:

You can notice the effort in these. The construction method is well applied in all plants and the flow of each shape is adequate.

The error I can notice here is more related to the very abrasive textures.

As in the mushroom, where you are outlining each shape that composes the texture.

We should draw the texture implicitly. That is, just draw the shadows of the shapes in the texture. As shown here: https://drawabox.com/lesson/2/6/drawingforms

BTW: What I mentioned about the leaves and branches exercises, will apply here just the same.

Homework:

Since there are a few errors to correct, I'll leave you some homework.

Don't overstress yourself in doing it. All this is a bit complicated and time consuming. Be patient and take your time.
