Hi! Good job on finishing your homework.

Funny that this was uploaded on my birthday, hehe.

Let's go by categories:

Arrows: Nice job here. The line quality is accurate and so are the creases.

A correct application of shading and line weight...

Branches: There are few loose tails on these, which is acceptable.

That wobble in the lines will diminish over time, this is normal as you perform new exercises.

You are already changing the degree of the ellipses on each branch, plus try to exaggerate the change a bit. You will get more depth.

Leaves: Excellent basic construction. Texture a bit excessive...

Any texture you work into the leaf should be not just a line, but a shadow cast. At least for this task.

So when adding it, even if it's very thin, remember to render it with a bit of line weight so it's noticeable as a shadow.

You don't need a lot of texture on the leaves, anyway.

Drawings of plants:

I can comment the same as I mentioned on the leaves: "Excellent basic construction, excessive detail."

There is a good handling of shape in these. The spherical and concave shapes as in the mushroom or the cactus are correctly represented.

Putting too many lines or textures inside the shapes makes you lose some of the solidity you achieved. I recommend to keep using textures, but moderately...

That shadow on the edge of the "mouth" of the pitcher plant, it's made with lots of little strokes. It causes a lot of visual noise that could be avoided by simply filling the area with pure black; that's more efficient.

Conclusion: There is a very good result. You have understood the basics of the lesson... I don't even have to leave you homework.

Keep on improving your branches in warm-ups, and be moderate when adding textures.
