Hi, I will try to give you a constructive critique. I see you're waiting since a while...

Arrows: when you look at the whole page, they look very good. And globally we have a good sense of space. However, as I zoom a little more, I see on the first page some woobly lines and the shadows are a little scribbly. Maybe some hesitation when applying line weight. The second page is better

Sausages: Very nice job !! your outlines are so clean! How do you do that? And the ellipses seem to be drawn with confidence ! Maybe on one or other you could vary the degree of the ellipses a bit more (like the 2 on bottom left from the first page).

Texture analysis: It is clear you understood this exercise, your analysis notes are relevant.

Your transitiosn to pure white are very good. Your transitions to black are maybe too sudden (I had the same difficulty...). Maybe try looking at the exemples shown in the lessons again, or other submissions from other students.

I also noticed that the edges of the areas filled with black are too irregular, and so are some lines. if they had been less wobbly the textures would look so much better. You could try outlining first the shapes you target to fill with black to make sure the edges are confident and smooth, and then fill them.

Dissections: the textures here are better than in the texture analysis exercise, even if the lines are still woobly. I think, you can achieve a better line quality (as on your second arrows page and first sausage page). Maybe it's a matter of patience. You can try to do only 2 dissection but with your better line quality, and clean, precise cast shadows.

2 other things :

• you can push the further the transitions in black.

• I can see that you're tacking care on the silhouette, and that a good point. But sometimes (for example, the treebark, Litchi and drymud), It looks like the silhouette was added at the last moment, but not really integrated with the rest of the texture.

Form intersections: Your lines are very goods and we feel the confidence in the marks.

The intersections themselves look good.

For your cylinders I notice that you're interverting de degrees of the ellipses. I mean, the most far away ellipse must have the biggest degree (be wider) than the one near us.

Good job !

Organic intersections: Tridimensionally speaking, the piles look good. Though the cast shadows could be thicker.

And i'm a little confused on what really happens on top left of the first page, but globally it looks very good !

Your line quality is good, except for the edges of the cast shadows, as mentioned earlier, maybe you should outlining first the shapes you target and then filling it in black.

I hope these comments will help you in your draftman journey !
