Starting with your arrows, you've done a great job of executing these with confidence, and pushing the sense of fluidity and movement. That carries over nicely to your leaves, where you've captured not only how they individually sit in space, but also how they move through the space they occupy.

When it comes to building up edge detail on your leaves, there are some where you're doing so well - building up with individual marks coming off the simpler edge and returning to it - though continue to work on getting them to blend into that earlier stroke more seamlessly, and avoid making those additions darker. There's also one case here where you approached it by zigzagging back and forth across the previous edge, effectively replacing it rather than building upon it. As explained here, this approach is incorrect.

Mvoing onto your branches, it appears that you may have misinterpreted the instructions for this exercise. In the instructions you're told to draw your segments from one ellipse, past the second, and halfway to the third, then start the next segment at the second ellipse, repeating from there. This is meant to provide a healthy overlap between the segments, which allows us to transition more smoothly and seamlessly from one to the next. You only overlap them minimally, resulting in a more sudden transition each time. Be sure to read and follow the instructions more closely in the future.

Now, continuing onto the plant constructions, overall you have done a pretty good job throughout these. You are definitely at times a little overzealous with the use of contour lines (there's really no need to turn your plants into wireframe models - contour lines suffer from diminishing returns, so it isn't always beneficial to pile on a lot of them), but all in all you approach construction quite effectively throughout, and you've done a good job of building those objects up from simple forms, and through the application of the leaf construction method.

I have just two minor points to draw to your attention, but they're rather nitpicky:

• On your flower pots, be sure to always draw the "thickness" of the rim by placing an ellipse inside of the topmost one. You do this correctly on this page, but not in the others. Also, placing an ellipse for the level of the soil can be helpful too.

• You do this correctly in most other places, but in this plant you neglected to draw each petal in its entirety. This is important because each of these drawings is just an exercise in spatial reasoning, and in order to fully grasp how each petal exists in space and how they relate to one another, we have to draw them in their entirety. After all, an object doesn't cease to exist where we can no longer see it.

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