It's hard to see because the page is a little blurry but it seems that the shading is kind of patchy, I recommend to shade with a bunch of ghosted straight lines.
I'd also recommend to vary your arrows' widths more so that you get a better feel of arrows.
Overall there is good confidence in your lines.
Might be a little personal preference but I would advise you to focus more on the outline of a leaf rather than detail because (as you know from L2's dissections) silhouette is a pretty powerful tool to use.
The middle leaf (with ???) actually makes sense, you just added a lineweight to a wrong lines
Keep them constantly wide. If you feel like a stroke is too big for you to achieve, you can add another ellipse in between.
Also keep in mind that if you are struggling with maintaining nice branches, you don't have to do forking branches.
The mushroom (page 1) seems wobbly. To avoid this, draw a straight line first and then ensure that ellipses are centered to this line. (since your other plants don't have this problem, I guess it's not an issue anymore)
The pitcher plant (page 2) lines are unconfident. Don't be afraid to add as much ellipses you need to make sure that you follow your form well.
Bottom plant (page 2) has scratchy outline on the leaves. Make sure that you work additive (you add on top on existing forms, not cut in) and that you execute your marks with confidence and don't do it randomly (https://drawabox.com/lesson/3/2/zigzag explains this point)
In 7th page your branches are oddly connected, you should make a ball in the intersection and then branch off that ball (just like in the branch exercise)
I believe that you definitely need to do some more branches. Add them to your warmup.
To make your leaves more 3d, it helps to add these leaf veins.
Try to work additive and don't zigzag your edges https://drawabox.com/lesson/3/2/zigzag
Your leaves' exercise was done well but this didn't translate so well in the plants you drew because they were less confident and there appeared some mistakes that I've mentioned before. I suspect that this might be due you not wanting to ruin your image but keep in mind that you are here to learn, not to draw pretty pictures and also confidence >> precision.
Do 1 page of branches and 1 page of leaves (focus on the leaves that weren't as successful in demos).
