Arrows: Very solid work here, not much to say. The only thing you could do is be consistent with your hatching lines, by ghosting every hatching line so they don’t overstep the boundaries of the arrow and they reach each side of the arrow instead of being short.

Sausages: These look great for the most part! The one thing is that the degrees of your ellipses don’t increase as much as they should when they reach the ends of the sausage.

It needs to look like this: https://d15v304a6xpq4b.cloudfront.net/lesson_images/061ed3b6.jpg

And not like this: https://d15v304a6xpq4b.cloudfront.net/lesson_images/6822fd02.jpg

I also notice that most of the sausages have only 3 ellipses, I would always go for about 5-6 ellipses. Having more ellipses will also help you change the degrees more accurately. The other thing is that some of your ellipses look a bit messy, if you are having trouble I would recommend practicing some ellipse exercises using the ghosting method. Remember to draw through the ellipse 2-3 (preferably only 2) times.

Texture analysis: On two of the three exercise, the black bar on the left is especially evident. The transition from dark to light should be more gradual, and the black bar should be less noticable. Here is an example:

Dissections: No comments here, these look great.

Form intersections: These are also great, nice job.

Organic intersections: The only thing to consider here is that on one of the organic intersections exercise (the vertical one), the sausage forms don’t really look like they are resting on top of eachother, but they look like they are going through each other. You fixed this in the next exercise, which looks much more like they are resting on top of eachother and sagging due to gravity. So nice job recognising your mistake.
