Hi,
your organic arrows are pretty good but they are slightly inaccurate.
In the organic forms with contour lines some lines are insecure. Keep in mind to use the ghosting method and to do the lines without fear in one movement of the arm (especially when you draw ellipses).
In the texture analysis your exercise lacks details : you have to be more careful to grasp the texture and all the tiny lines that define the shape of what you draw (the texture is never random).
Also don't be afraid to cast shadows (also in the dissection exercise). When needed use the black without fear; visualize in your mind the form of your texture in tree dimensions! (that will help you to know where to cast your shadows).
Besides that the dissection exercise is well done (the perspective of the dissection in the first page at the bottom right is wrong).
The form intersection exercise is good but you went over the lines too many times (also there try to visualize the forms in three dimension, it is difficult but it will help).
Your organic intersections have wobbly lines and some shadows are missing.
Your major mistake were the insecure lines; try to redo some exercises of lesson 1 to make lines straighter and more confidently.
Try to think about the shadows that you're casting, observe in the real world how the objects are casting their shadows and watch carefully the textures around you: your skin, the fabric of your clothes, the wood of which the pencils are made...
Observe everything with scrupulous attention and you will draw with more accuracy and realism!
I hope that my review will help you, good luck!!
Next Steps:
Do some pages of ghosted lines and funnels from lesson 1 (until you feel confident) and any exercise that you think will help you to gain more confidence in your lines.
Do another pages of dissections (lesson 2) and remember to cast shadows!
Remember the 50 percent rule: at least half of the time you spend drawing must be devoted to drawing purely for its own sake.
