Arrows

Pretty confident and good, to improve them, you can try to exaggerate more how they get bigger as they get closer towards the viewer, more exponentially. The lineweight added in your overlaps is a bit stiff too, remember you should do it with a single superimposed line drawn from the shoulder.

Hatching seems a bit rushed too, so remember to take your time with each mark.

Organic forms

Pretty good in general, you got a few that are a bit stretched ellipse-like, and some pinching a bit, so remember that they have to be 2 identicall balls connected by a tube of consistent width. Ellipses and curves get a bit wobbly at times, but pretty confident in general. Remember that confidence is more important than accuracy, don't hesitate to sacrifice accuracy to get those as confident as you can.

Textures

Pretty good job in general. There are a few places where you focus a bit on contours, so remember that we should only draw cast shadows.

Form intersections

A few things.

1. Don't repeat lines, even if they're wrong.

2. Hatching is a bit rushed, take your time

3. Don't forget to place starting and ending point before drawing each line, and to ghost it, it looks like you've been rushing those pages, you should be doing your best on every page of the homework, if you feel like you're rushing, take a break and come up later.

4. Main objective of this exercise is to draw forms in a cohesive manner in space, by mantaining consistent foreshortening on them. To do that it's better if you focus in shallow perspective forms, as they are easier to handle.

Organic intersections

Pretty good and solid in general, great job! There are some places where the shadows look like they might be sticking a bit to the forms, so careful on that.
