Pleased to meet you again, Flippy! I'll be getting right into your submission now.

Branches

I can clearly see your sign of improvement from this resubmission. You're drawing past your ellipses 2-3 times as requested, and you attempted to follow the flow lines of the curve nicely. On top of that, you're doing a decent job at hiding visible trail on compound stroke too. There's certain point I would like you to pay more attention on, though.

Firstly, don't forget how those ellipses turn in space. Ellipses will get bigger or narrow depending on where you want the viewesr eyes to be.

Another Demo about the same principle I've done for student (Not official demo, but you might want to pay attention to them regardless.)

Secondly, you should try practicing those ellipses more to make sure they're roughly the same sizes. So that your branches lines will properly touch them without leaving some floating ellipses inside. This'll probably help most of the floating ellipses you have now.

Side notes : I believe accuracy is also another point I wanted to mentioned, However this'll come with times so there's probably no need for me to mentioned it. You should be giving it some attention too, though. (accuracy of your branches lines and how well they match flow lines)

Plants

One thing I can say for certain is that those plants are well constructed. Those forms are confidently drawn and certainly helps to illustrate how objects are 3d instead of lines on a page.

Now there's some points I've certainly want to mention and I'll be mentioning them down here.

"I gave a little bit of detail to the outline because I understood from the demos that this is different from texture."

If you wouldn't mind, could you please link the demos below? I've not heard of any demo that advocate for giving details on the outlines. (excepts leaves.) In fact, it's actually one of something Drawabox discouraged their students to do because It'll take away from the smoothness and the confident of the form. Regarding Clean-up

Line weight are mainly use to emphasize which form advances or recedes toward the viewer. In the context of this course, at least. Overlapping leaves with line weight

Secondly, for your Fortunella Crassifolia, you could probably use contour lines instead of ellipses here. They're certainly believable, but contour will probably be a better option here. Common pitfalls

Thirdly, even if the form aren't in view of the viewers, draw them regardless. I saw this mistake in your some of your branches where you didn't draw their other ends. Without properly defining those connecting, It'll be much easier for us to assume that what we're drwaing is simply a flat line on a page instead of actual 3d form.

Suggestion : Lastly, for your leaves it might be better for you to work additively instead of subtractively. Right now in some of your leaves you're cutting into your form, and, as a result, makes some of the construction felts a little flat. It isn't wrong to use them, but you probably want to limit it as much as possible. https://drawabox.com/lesson/3/8/complexleafstructures
