Hello there I call myself Quat and I am going to review your exercises for lesson 3 today.

First of all the organic arrows exercise: You seem to have followed the instructions well enough, although some of your lines are wobbly and unconfidant , which is something I noticed across your submission.

Secondly the leaves exercise: The first thing I noticed was that you only drew 6 leaves. While there isn't any required amount that must be reached, but I think that having more leaves would allow you to experiment more .

I also noticed that none of your leaves have contour lines in them. It isn't regarded as a common mistake in the lesson, but they are essential to understanding how the leaves are formed in 3d space .

also one of the leaves show texture in one side but not in the other which is not how leaves work .

next the branches exercise: The first thing that I noticed was that a lot of the branches the branches are wobbly and unconfidant. I think that the reason for that was that you might have focused more on making the tail invisible rather than making your lines smooth and confidant .

I also noticed that a lot of your branches have Ellipses that don't change their degree you can look at the Branches demo as an example of the degree changing correctly.

Next is the plant section of lesson 3: here I noticed that most plants suffer from the same problem, that being the wobbliness of the branches. You seem to be struggling with drawing them confidantly.

I also noticed that the cactus drawing lacks any sort of construction line and I am going to make redo the same kind of cactus, and if you are confused over how would this cactus be constructed, I would recommend applying the concept from The cactus demo and The mushroom demo
