Overall you've done a pretty good job. While there's room for improvement, and that will certainly come with continued practice with observing your references more carefully to find more nuanced features and elements, as well as just getting used to drawing confidently, always pushing the flow of your lines and shapes and ultimately focusing on capturing each form such that it feels solid and three dimensional, you are moving in the right direction with each and every one of these points.

Starting with your arrows, these are flowing nicely through 3D space, and are applying perspective to both the positive space and the negative space in order to show a great sense of depth within the scene. You continue to apply this fairly well to your leaves, where you capture the sense of how the leaves move through the space they occupy, instead of focusing entirely on how they exist statically within space. You are also adhering nicely to the constructional process, adding additional details on top of the existing structure, and letting it adhere directly rather than treating previous phases of construction as more of a suggestion or a loose sketch. By adding those edge details such that they come off the simpler edge, and then return to it as individual spikes and waves, you're reinforcing the idea that the leaf is solid and three dimensional.

Moving onto your branches, there are some shortcomings in how you're applying the technique that are getting in the way. Most specifically, you're not extending your segments fully halfway towards the next ellipse. What you should be doing here is drawing an edge from one ellipse, past the second, and halfway towards the third. Then your following segment would go from the second, past the third, and halfway towards the fourth. As a result, you'd end up overlapping that last chunk of the first segment, allowing us to use it as a runway before shooting off towards the next target. This in turn allows for those segments to flow smoothly into one another, giving the impression of a single, seamless, continuous stroke, with the control of something more broken up.

Moving onto your plant constructions, and starting with your Tomato, your approach here was pretty good, though I think that starting the tomato off as more of a ball form (rather than a series of stacked ellipses all connected together probably would have yielded better results. Making a ball form feel three dimensional is as simple as drawing an even, smooth ellipse, and adding to it a contour ellipse along one "pole" as shown here.

For your voodoo lily, just a couple small points. You're mostly doing a good job of adhering to the underlying phase of construction when adding the more complex edge detail, although you should work to get your additional edge detail to blend with your existing edge where possible. Right now it's very visible where those next strokes start and end, as they do so quite suddenly. Drawing them with a more confident pace and while applying less pressure will allow the strokes to taper more towards either end, giving you an easier time of integrating and blending them into the existing edge.

Also, I'm unsure of what the filled areas of black are meant to represent - I'm assuming they're cast shadows of some sort, (possibly the middle of the lily for the top one and the leaf itself casting down onto the body of the flower for the second, but these are very unclear). In the off-chance that they're not cast shadows and that you're maybe trying to capture something in the drawing that shows up as being coloured black, always remember that we want to save our "filled" shapes for cast shadows only. Again, I'm convinced that you were doing that, but I had to mention it just in case.

Continuing on down, I think you have some really nice success with your balloon flower, and things continue to improve through to the daisy and blueberries.

I have just one last thing to point out - since most of these drawings are cropped quite tightly, I can't get a sense of scale on them. In the case that you're drawing smaller (which some of these, especially the tomato suggested you might be due to the relative thickness of the lines), always push yourself to take full advantage of the space available to you on the page. This will engage more of your brain's spatial reasoning skills, while also pushing you to use more of your whole arm when drawing your lines.

So, I'll go ahead and mark this lesson as complete. Keep up the good work.
