You're off to a good start with your arrows, capturing how they move through space with a strong sense of fluidity and motion. This carries over quite well into your leaves - you're not only capturing how they sit in space, but also how they move through the space they occupy.

While you do appear to be building up more complex edge detail correctly, I noticed for the leaf in the upper left corner that it seemed like you were redrawing parts of the leaf that didn't really need to change. Remember that constructional drawing is all about building upon the existing structure, step by step, to achieve greater complexity. As shown here, if a mark from an earlier phase of construction adequately captures a certain part of the structure, its lines can stand for themselves and do not need to be replaced. You appeared to be doing this correctly in many of your drawings, but I still wanted to call it out.

Additionally, for the central leaf with the wavier, more erratic edge detail, I probably would have tried to build this additively (that is, extending it off the simple leaf rather than cutting back into it subtractively) in order to maintain a stronger overall relationship with the existing structure.

Continuing onto your branches, nice work! You appear to be extending your segments fully halfway to the next ellipse in most cases (though there are a handful where you don't, so be more careful with that). Additionally, take more care to overlap the previous segment's last chunk directly, using it as a runway, when adding the next segment as shown here.

Looking at your plant constructions, as a whole you're doing quite well. I just have a few things to call out:

• For the hibiscus drawing I'm not seeing any signs that you actually approached it starting with the flow lines to establish how each petal moves through space. The steps introduced in the leaf construction exercise are important - each one breaks the overall problem into solving one issue at a time, starting by establishing how the leaves and petals actually flow through three dimensions. Every answer given at each stage of construction must also be followed, rather than contradicted. So for instance, the ellipse we start with for the hibiscus establishes the perimeter to which each petal would extend - and so we need to make sure that our flow lines stop right at that border, and that each petal is only as long as its own flow line, stopping at its tip and leaving no arbitrary gaps or unclear relationships.

• For your potato plant, be sure to actually follow any demonstration you follow to completion. Here you left out the cast shadows that each leaf would cast upon the ground. The filled area of solid black in the center is itself just cast shadows (we wouldn't just arbtirarily fill the negative space in with black within this course), but without the added context of having every form cast its own shadows, we lose that impression.

• The leaves on this plant end up falling into the issue of zigzagging their edge detail, resulting in very loose, unclear relationships between the different phases of construction. Again - construction is about solving one problem at a time. If you break away from the existing structure, you end up trying to re-solve issues that have already been addressed, and in doing so, you lose the advantage of having them already sorted. Generally speaking, the flow line establishes how the leaf moves through space, then the simple leaf silhouette/footprint extends that into three dimensions, creating a basic flat form that moves through that space. Finally, we just have to add each individual bump of edge variation to the existing edges, only concerning ourselves with how they bump upwards or downwards, not how the leaf as a whole moves through space.

• A very minor point about this last one - treat your objects for this course as though they're all covered in white. Do not try to capture any local colour/patterning, and reserve your areas of solid black only for cast shadow shapes.

Aside from that, your work is coming along well. I'll go ahead and mark this lesson as complete.
