Starting with your arrows, these are drawn with a good deal of confidence, capturing a sense of how the arrows move fluidly through the scene. You're also generally doing a good job of compressing the spacing between the zigzagging sections to show the depth in the scene, although in the bottom left arrow, the end with the arrow head could probably stand to overlap more.

Continuing onto your leaves exercise, you're carrying through with the same sort of confidence and fluidity, capturing not only how the leaves sit in space, but also how they move through the space they occupy. I'm also quite pleased with the way you're building up more complex edge detail, and how when adding texture you're focusing on the shadows cast by the veins as textural forms, rather than trying to draw the veins themselves.

One thing you'll want to explore more on your own is the more complex leaf structures, but as it stands you're doing a good job.

Moving onto your branches, I'm noticing one major issue - it seems that when you start your next edge segment, you're doing so where the previous one ended, instead of starting back at the previous ellipse as shown here in the instructions. The overlap that results when doing this correctly is important, because it helps us transition more smoothly and seamlessly from one segment to the next. Take more care when reading through the instructions in the future.

Looking at your plant constructions, there are a few little hiccups but overall you're doing a good job in building your constructions up piece by piece, maintaining solidity between each stage of the process. The few issues there are do end up undermining this in some places (and I'll address them each in a moment), but overall you're doing well.

• The first issue is that while you handled edge detail quite well in the leaves exercise, you appear to have broken away from this, opting to zigzag your edge detail in most cases with wavier edges, like the hibiscus on this page. This breaks the third principle of markmaking. You need to be breaking these into smaller segments which are built directly onto the previous phase of construction.

• On the same page, in the plant on the far right of the page, when adding the greater complexity to the larger leaf there, you appear to have redrawn the entire leaf, effectively replacing the previous phase of construction. Construction is not about redrawing the object from phase to phase, abandoning everything that precedes it. It's about building upon the previous structure, adding the parts that change, and leaving the parts that don't. This leaf should have been built up more like this.

• For the raspberries, you ended up getting kind of loose/sketchy with the little balls you were attaching to the form. When it comes to the silhouettes of our forms, it's important to keep them fully enclosed, in order to make sure the object reads as a solid entity, and not just a series of loose lines clumped together. From there, you can draw your little cast shadow shapes by first outlining them, then filling them in, instead of trying to 'paint' them on stroke by stroke. This will afford you greater control in their execution.

Aside from that, your work is coming along well. Be sure to keep those points, along with the correction regarding your branches exercise in mind. I'll go ahead and mark this lesson as complete.
