To start, you've done a pretty good job with your arrows, maintaining their sense of flow and fluidity. With #3 though, the viewer's getting mixed signals in terms of which end is which, due to that massive gap at the rear end of the error. Remember to keep compressing those gaps as they go further back in space.

Looking at the leaves, you've got a decent start, although some of these are definitely twisting a lot more sharply and dramatically than they probably should. Remember that we're drawing leaves being gently pushed this way and that by the wind, not forms being actively twisted by human hands, or by a hurricane. Also, you don't appear to have made any attempt to move beyond the simple leaf forms, to construct greater complexity on top of them. Because you generally approach this well in your later drawings, I won't stress the point too much, but in the future please follow through all steps of a given exercise, not just the most basic ones. Also, it would be worthwhile for yourself to explore more complex leaf constructions, like those shown here and here.

Moving onto your branches, you've got the basic premise down pretty well, but you're falling short in one significant fashion - you're not extending your segments fully halfway towards the next ellipse. Instead, you pretty consistently seem to be extending them just barely past the previous ellipse. As shown here, getting halfway to the next provides with a good deal of runway to overlap for the next stroke, allowing for the two strokes to flow more seamlessly together.

For your plant constructions, you've largely done a good job, but there are a number of small shortcomings or issues in how you're approaching things or following the instructions that I'd like to address:

• The issue with the branch segments not extending far enough is present in a number of places, most notably in this one where it results in a lot of jerky transitions from section to section. Also, you didn't draw through your ellipses, which you're required to do for each and every ellipse you draw.

• Make sure you draw through all your forms. You generally do a good job of this, though you ended up cutting off the stem of this flower where it gets overlapped by a leaf. You should be drawing each form in its entirety so you can better grasp how each form exists in relation to its neighbours.

• You have a pretty strong habit, when getting into the "detail phase" of things, to confuse texture with just making the drawing pretty. Every part of our drawings serves to communicate something to the viewer. Through the construction, we establish how one might manipulate a given object in their hands. Through texture, we convey how it might feel to run one's fingers over the various surfaces of that object. Shading, as described back in lesson 2, should not be included because it doesn't actually serve any purpose within these drawings beyond being decoration. Often people will look to shading to imply that a form is three dimensional, but we already have constructional techniques which are far more effective at accomplishing that. Don't look at the detail phase as being one to just make the drawing impressive - focus always on the specific purpose, the goal you're trying to achieve, and what it is for. And of course, form shading should not be confused with cast shadows, which we use quite a bit to imply the presence of textural forms.

• In this drawing, you approached the frilly edges around the cups incorrectly. You drew those wavy edges without appropriate structure to support them, effectively jumping into a more complex level of construction too early. Don't skip steps - a wavy line is, at its simplest form, a smooth stroke as shown here. Start with the smooth stroke, then build the individual ripples on top of it.

• Lastly, a minor point about this plant - actually, rather its pot. You've actually drawn this really well, but you should have drawn through the box form of the pot, so you could fully understand how it exists in 3D space, rather than just as a flat element of a flat drawing. Remember that these exercises are at their core about training you to think in 3D space - the extra lines of construction, drawing through forms, etc. are critical to that.

All in all, despite my points here you have done a pretty good job with most of these. There is room for improvement, but all in all you're doing fairly well. I'll go ahead and mark this lesson as complete.
