Starting with your arrows, they're generally flowing quite nicely across the page, though what jumps out at me is that you're still pretty hesitant when it comes to getting the zigzagging sections of ribbon to actually overlap one another. As we look farther back, the spacing between those sections will visibly compress due to perspective, and quite soon overlapping is inevitable if you want to convey a natural sense of depth within the scene.

For the most part you've got a good start on your leaves exercise - they're flowing very fluidly with nice, confident linework. I do believe you're still somewhat focusing on how the lines themselves exist on the surface of the page however (and this becomes doubly so when you start adding bits of texture to them, as there's no sign that the little speckles you've drawn actually get closer together on the farther end of the leaf compared to the closer end. Overall, you do need to be more aware of how you're placing a form within a three dimensional space, thinking about how those initial flow lines actually pierce through the depth of the scene, not just gliding across the flat page itself. Additionally, when it comes to texture, I strongly encourage you to use reference imagery more directly, as currently what you've done here is largely quite simplified, and doesn't reflect the natural world as accurately as you would hope. I've actually rewritten all of lesson 2's texture section, along with new videos, and I'd like you to review it to get a better sense of how all this should be approached.

Your branches are definitely moving in the right direction, with a couple small pitfalls:

  • The degree of your ellipses appears to remain fairly consistent in most cases, rather than shifting naturally from narrow to wide, or wide to narrow, based on how the circular cross-section it represents sits in space relative to the viewer. This is an issue I mentioned when critiquing your lesson 2's organic forms with contour lines exercise, so refer back to that critique.

  • Make sure you extend each segment a full halfway to its next ellipse (you're doing this most of the time, but there were a couple that didn't extend far enough. It was definitely just a slipup, you're generally quite good at this, but I figured it was worth mentioning.

  • When drawing the following segment, try to use the previous one's last chunk as a sort of runway, overlapping it directly before shooting off to your next goal.

For your plant constructions, I feel that overall you've actually done a better job than your initial exercises might suggest. You're very mindful of approaching the constructions step by step, building upon the previous phases and adhering to the decisions you'd made previously. There are a few concerns but overall you're doing reasonably well.

  • The first thing that jumps out at me is that you have a tendency to draw rather small. This can mean that you're simply not taking full advantage of the space on the page, or that you're choosing to draw the entirety of a plant that has many repeating elements, rather than focusing on on just one and devoting more space to it. In this one you're doing both - there's plenty of room above, below and to the sides of the drawing, but it's been cramped right in the center. You also could have chosen to focus in on just one or two of these, which would have given you a lot more room to think through the spatial problems involved. Drawing small is a common issue for students that causes them to shoot themselves in the foot somewhat - it limits their ability to work through those problems, and in turn makes it much harder than it needs to be.

  • There are several cases where your linework definitely becomes problematic when you build up additional strokes on top of one another. I know you're capable of drawing confidently, executing each stroke with the ghosting method and doing so in a mindful manner, but ther eare cases where the stuff along the top of this drawing occurs. Here it looks like a mixture of trying to correct mistakes (which you should simply not do - if you mess up, don't try to fix it, as this will only pile more ink onto the problematic area), and attempting to add line weight. As far as line weight goes, you definitely need to limit how much of the existing line you're adding weight to, as you're struggling to keep the line on top of the path it's following ,while remaining confident. Remember that we apply the ghosting method even here to keep our lines confident and accurate, and in general, keep in mind that line weight only needs to be applied to limited sections to clarify overlaps. I think you do get this, since you're not trying to reinforce the entirety of petals and leaves, but you're definitely choosing to reinforce sections that are much longer than they necessarily need to be. Continuing to practice your super imposed lines exercise as part of your warmups will help, though you can modify it such that you perhaps just draw through the middle half of the guideline, instead of following it the whole way through. This can help you practice having the weight blend seamlessly with your existing line.

  • I definitely feel that this drawing ended up vastly simplified relative to the actual reference image, and that you ended up focusing much more on simple 2D shapes rather than thinking about the forms you were constructing. It definitely stands apart from the other drawings you've done.

All in all, there's plenty of room for improvement, but you are moving in the right direction. Be sure to continue practicing and addressing what I've said here, but I do think I will mark this lesson as complete, as you can continue to work on it through into the next lesson.
