Hello!

I will start correcting your lesson:

Arrows:

• These are fine; there is a clear sense of depth. The way they fold in space is also accurate.

• Still, I would like you to pay more attention to the shadow lines inside the arrows. You should do them more meditatively, to avoid them going off the edges or being overused. They have become a bit erratic.

Branches:

• Excellent. The lines are almost not out of place, and will get better with practice. Ellipses are well aligned and change degree with respect to their position correctly.

• Branches that split in two are also well done, you followed each step well.

Leaves:

• These fold back on themselves correctly. How you have added the detail on the bases, constructively, is also appropriate.

• Both here and in the other plant drawings, the way you draw their interior detail could be improved.

Things like the "veins" inside the leaves are not to be worked in as mere lines.

What we should project from these are only their cast shadows.

Thus, we do not destroy the three-dimensionality of our drawing by adding details or empty lines.

This diagram may help.

Plants:

• Regarding these, the constructive method is well applied.

Leaves, branches are as well applied as in the previous exercises.

• As I usually tell most people who start this lesson, try to moderate the use of shadows and areas of pure black.

There is always a tendency to overuse them. In your case, the shadows of the spheres inside that cactus are so large that they give unnecessary contrast.

• Which brings me to the consistency of the shadows. In the cactus balls themselves, some shadows are cast to the right and sometimes to the left, breaking the consistency of the light. This destroys the "reality" of the drawing.

If the light comes from the left, all the shadows will go to the right. Of course there are exceptions to this, but let's work this way for now so as not to complicate things at the beginning.

• Also try to be more patient when working the detail of the silhouette and the lineweight that sometimes look a bit rushed, take your time to think about them like any other part of the drawing. If these details look erratic, you lose a lot of solidity of the drawing itself.

. I have nothing more to mention. Above all you have understood the basics of the lesson. The mistakes mentioned can be worked on as you go along.

Move on to the next lesson whenever you want!
