Hey there, you did really well! I hope my critique helps you!

Organic Arrows

Nice job with the tapering and shading the correct sides of the arrows. There is some three dimensionality. However, there is an issue with your lines: a lot of them are quite wobbly and fragmented, which has to be avoided. You must draw your arrows mostly from the shoulder – every side should be one confident sinusoidal curve. Occasionally there is too much weight which looks messy, but there are some arrows where it was used well. I can see your improvement with time :)

Organic forms with contour lines

You did a pretty good job here, changing the degrees of the ellipses and contours which is great! And you went through your ellipses 2-3 times, in addition to aligning them to the minor axis. You even have the hooks where the contours touch the edges – very nice!

Organic intersections

You did well, but some of the mentioned possible mistakes creeped into your work. You mostly made your shadows stick to the forms casting them – they should wrap around the forms they fall onto – this, for example, would be better. You did keep your forms mostly simple which is good, but you didn’t change the degrees (like in the Organic forms with contour lines) at all, which helps a lot with perspective and three dimensionality. And don’t leave the little white spaces in the areas that are supposed to be solid black. I know it’s tough, I too am guilty of it, but try to avoid it in the future as it tends to make drawings look messy and confusing.

Texture analysis

Looks good. You can afford to be more extreme with your shadow shapes, especially with the crumpled paper, the transition is very light – and it would’ve been better if you had titled the textures, I could have given you a more specific critique. Also, considering your second texture (and a bit of the paper), I think you used a lot of forms (outlines), which should be avoided in this exercise. I know you identified these as thin shadows, but perhaps they were the edges of shadows which tapered quickly? (if that is so, put the entire shadow in as a thin polygon, rather than a line, or just ignore the shadow if it’s that thin - like really old cameras do).

Dissections

I see that you applied what you learned from Texture analysis, which is great. I see that you tried to show the curvature of some sausage forms. You should be more extreme, like really extreme – don’t worry about the end result for now. This is practice, after all. You used a lot of lines in places of shadows, for example, the pumpkin texture. You can fix that by just adding some weight. Really try to communicate the shadows, even if they look like lines. You also rarely broke the silhouette because of the flatness (the textures weren’t curved enough). Try to curve them and break the silhouette.

Form Intersections

Your form intersections – the mixed box, sphere, pyramid and cone intersections – are very good, the lines are confident, you drew through your ellipses, and the intersections make sense. You could have added some more, but this is fine. The box intersections however are problematic – they are part of lines we’d see if the boxes were transparent, all of them are inverted, and look pretty much the same. Try to think about how these intersections would look like you did on the other two pages. It will show up later, so it’s important that you give it some more thought.
