Starting with your arrows, you're doing a great job of drawing these with a great deal of confidence, which really helps to sell the fluidity with which they're pushing through the world. This carries over very nicely into your leaves, where you're capturing not only how they sit statically in 3D space, but also how they move through the space they occupy. That said, while you're off to a great start with these leaves... you also appear to have stopped at step 2 of the leaves exercise, and neglected to work with any of the edge detail concepts in step 3. Only step 4 was actually optional, so I would consider this unfinished.

Continuing onto your branches, you've largely done a great job here - just be sure to extend your edge segments fully halfway to the next ellipse (as demonstrated here - it helps a great deal in achieving a smoother, more seamless transition from segment to segment), and keep in mind that the degree of your ellipses here should be getting wider as we move farther away from the viewer along the length of the tube, and as that tube actually turns through space. If you're unsure of what I mean by this, review the Lesson 1 ellipses video, where I demonstrate the concept with some props.

Moving onto your plant constructions, by and large your work here is really solid. You're making excellent use of the page, and are generally making solid use of the constructional principles, except for one area - and that's the area you skipped in the leaves exercise.

When adding edge detail to your leaves and flower petals, you jump between two different approaches. Either you'll add a lot of hesitant, timid marks as we can see here, which doesn't actually create an impression of a more complex structure that exists in 3D space, but rather really just comes down to some arbitrary marks being slapped onto the page. Or, you approach it more like this, where you're drawing more solid, continuous lines, but have a tendency to redraw a lot more of the petal's edge than you need to, and even zigzag back and forth across the previous edge with a single continuous stroke (which as I explain here should be avoided).

The thing to keep in mind is that construction is all about building up changes, one step at a time. We lay down the basic underlying structure, then build up whatever needs to change on top of it. We add these with relatively simple strokes each time, and in this case, much of the time we're extending out the leaf or petal's silhouette by adding a single stroke that seamlessly rises out of the existing edge, and returns to it. If we end up with gaps, or if this line happens to slip past the given edge, then that can weaken the relationship between the phases of construction (and ultimately break the illusion that we're looking at a single cohesive form for the leaf or petal as a whole).

Now in most cases, in a situation like this I think I would assign an extra page of leaves. But given that the rest of your work is so solidly done, I'm confident that you should be able to grasp the issues I've explained here, and address them on your own. So, instead I am going to mark this lesson as complete, and if you want to send over a page of leaves at some point for me to look over, you can do so as a reply to this critique. But you are not required to do so, and it does not have to be prior to moving onto the next lesson.

So! I'll go ahead and mark this lesson as complete.
