Aaaalrighty. Round two.

Starting with your arrows, these pages are admittedly pretty sparse (it's always nice to see people drawing big, but that first page with two arrows is pretty sad - second page is definitely better, and is what you should be aiming for when submitting pages for this exercise). They definitely flow quite nicely through space, and show a generally decent sense of depth. I think you got the hatching wrong on the second page's bottom right corner though - it suggests that the arrow is moving away from the viewer, despite getting larger. Not a crazy mistake though.

Your first couple pages of leaves - the ones without detail - definitely show a much stronger sense of flow and fluidity than the third page (when you started introducing detail). I suspect that knowing that you were going to add detail put you in a different frame of mind, and interfered with how you put down your marks.

When it comes to the edge detail, you're doing pretty well. You're building it right off the earlier phase of construction, so it feels solid and three dimensional. You do have issues however in adding internal detail. I'm not actually super concerned with that since it's not a major aspect of this lesson, but looking at this leaf and this one it's clear that you're not really using any solid reference for those textures, and if you are, you're spending most of your time working from your memory instead of continually looking back at your reference to draw directly from what you see there. Also, when it comes to drawing those veins along the surface of the first leaf I linked, you're outlining those forms, rather than capturing the shadow shapes that they cast on their surroundings. I'm glad that you're recognizing that the veins themselves are 3D forms and not just lines, but you appear to have forgotten most of what was covered in Lesson 2's texture section.

Make a point of rereading at least the following two sections, but really rereading the whole texture section would be worthwhile:

Moving onto your branches, you're doing a decent job here. You do still have some visible "tails" where the ends of segments veer off their intended path (this might be because you're trying to slow to stop - getting into the habit of lifting your pen off the page without slowing down may help with this). One other thing I wanted to point out was that you've got a lot of ellipses that have really wide degrees (suggesting that those cross-sections are pointing towards the viewer), but where the spacing between those ellipses suggests that the branch is moving across our field of vision. I figure you might be drawing the ellipses a bit more arbitrarily, so instead think of these two factors and what they say about the path the branch is following. As you can see here, if we imagine that the ellipses are equally spaced out in 3D space, then if they're narrow (and therefore moving across the viewer's field of view) then we're going to be able to see more of the space in between them. If they're wider however, and therefore moving through the depth of the scene, then we're not going to be able to see as much of the space between them, making them appear closer together.

Moving onto your plant constructions, you've got some shows of strengths and some areas of weakness. I'm pretty pleased with how you tackled the petals on this page - you stuck closely to that initial phase of construction where the petal was defined in much simpler terms, so when you added those cuts they still felt like they were part of a petal that moved through 3D space. I also felt that you handled the flow of the petals on this page really well - they feel very fluid and capture a strong sense that this flower exists in 3D space. Lastly, while this last one is pretty simple in terms of its flower pot not really having much to it (you should treat everything you draw with the same respect, even if the lesson itself is not about flower pots), the succulent's leaves feel quite well constructed and believable in how they move through 3D space. Also, I'm gladf that you built the flower pot around a central minor axis line.

Overall while there are some issues with construction here and there (I don't think the venus flytrap came out how you expected it to, but honestly it was a solid attempt), these are pretty normal mistakes that aren't a matter of what you do or don't understand. I think you do understand what you should be aiming for now. My biggest concern in your drawings really just comes back to how you tackle detail and texture - so the points that I raised back with your leaves are definitely things you should be sure to address, rereading those sections from Lesson 2 and maybe going over them every now and then to make sure you don't forget.

Aside from that, I'm relatively pleased with your results. I'll go ahead and mark this lesson as complete.
