Hi Luny! Hope you're doing well.

Organic Arrows

  • Your arrows are smooth & they're compressing & expanding as they move away & tworads the viewer.

  • Edges of one of the arrows is not overlaping which made that arrow more flat(see https://drawabox.com/lesson/2/4/overlap) & in one of the other arrow the second curve is vastly different from the inital curve, which make it look a bit unnatural(see https://drawabox.com/lesson/2/4/step2).

  • Good work on the lineweight, I can see that you've applied them on the overlapping section to hightlight what's in front.

Leaves

  • For most part your leaves are following their flow line. Some of the folding ones are not natural & feels stiff in a way but I see that you did improve on it, so keep practicing them.

  • Nice work on breaking the silhouette of these leaves, though I like to remind you that it's recommended to do those construction using addition whenever possible, if you've to subtract part of the leaves then you'll have to consider whether it's raised or lowered relatively in the space.

Branches

  • Sometimes the ellipses here are not perpendicular to their minor axis(along with not cutting the ellipses in half), see https://drawabox.com/lesson/1/5/minoraxis. Ghost multiple time before placing the mark for them, if they're not placed well they can break the construction(here the branches) instantly.

  • If you're having trouble with curves of the flow line, then I recommend placing an ellipse at the peak of the curve(perpendicular to it), it would help you place the edges of branch easily.

  • You're gradually changing the degree of the ellipse, there are some cases(like in top right branch) where the change is drastic, see if you can avoid these as much as possible.

  • Sometime the edges of the branches are going astray, with enough practice you will get better on this.

Plants Drawings

  • In the sunflower drawing, you've drawn beyond the planned boundary. This can happen when the planned ellipse is in wrong place or different size than of the reference. You'll want to adjust other stuff to it or draw a new boundary & then draw petals within it

  • In the potato plant demo, I see that you didn't drew throgh the leaves. Don't worry about construction looking messy, it's bound to happen with complex drawings, just take one step at a time & draw through your forms & each flow line for these leaves.

  • You're doing the constructions in page 3 & 4 using the basic shapes. Don't be afraid to use a flow line for big shapes(other than leaves, branches, petals) as well, if you feel like egg plant could use a consistent flow, then use it.

  • I like to remind you again that you're not drawing through the forms(page 6), it's important that you draw all the construction line so you can develop better understanding. You can use lineweight or cast shadow to make even complex construction easy to understand.

Overall

You making great progress on these constructions. You do need to work on drawing through forms, keep them in mind when doing future lessons.
