Hi HIRAEJAZ!

Congratulations on completing Lesson 2! Overall, you're off to a pretty good start.

Organic Arrows:

Well done, your arrows are generally drawn in confident strokes and with attention to perspective. However, don't be afraid to push it and explore different types of directions and overlaps next time you attempt this exercise. Also, I notice that you try to correct errant lines. Don't do that, leave them be and try again with your next arrow.

When applying line weight, avoid wobbly and chicken-scratchy lines, instead take your time to ghost a new line on top of the first one and execute it in one confident stroke. Pay attention to your hatching too, because sometimes you draw it in the wrong side of the overlap, you might want to reread the section on arrows to clarify that a little.

Organic Forms with Contour Lines:

Overall, you manage to keep the forms of the sausages consistent. Ellipses and contours are generally aligned to the minor axis, the exceptions of this are few. Try to focus more on executing your ellipses confidently; for now they are a bit wobbly and not drawn through 2 times, which you should do. Even though you generally manage to keep them in their allotted spaces, remember that confidence is prioritized over accuracy. Meaning, you should take your time to ghost and draw your ellipses confidently, and it's OK if they don't fit into their places nicely if they are confident. After you become better at drawing confidently, you can focus on improving accuracy. Try to be more bold with changing the degrees of your contours and ellipses because for now they change only slightly.

Texture Analysis:

Good job on your textures! You draw them by using shadow shapes and convey the transition from dark to light successfully, congrats on a very successful first attempt.

Dissections:

Nice job on that as well! You're very thorough in your attempts to transfer a texture onto a 3D form. However, be mindful of the way texture wraps around the form, as in some of your examples dissections look very flat and 2D. Try to imagine additional contour curves around the form, along which texture details are situated, it might help you visualize a texture on a 3D form better. Also, don't forget to break the silhouette of the form because it helps to enhance this effect even further, it could improve some of your dissections (for example, bamboo, concrete and bricks). Try to be more implicit in your drawings too, focusing mainly on shadows and not transferring every explicit detail onto your drawing, try to keep this in mind in the future.

Form Intersections:

I would recommend that you work on your boxes and 3D shapes a bit more, because there's a number of mistakes with that, which makes the shapes looks a bit inconsistent, like they don't exist in the same space.

As for the intersections themselves, I'm afraid you have misunderstood the task a little, because there are very few of them. There are only cones that are intersecting in your work. Try rereading a section on form intersections and imagine how the forms cut into each other, which can be shown on the drawing with some additional lines. Simply applying line weight wouldn't be enough here, because it doesn't tell us anything about the way forms intersect, suggesting that they simply float next to each other.

Organic intersections:

The forms themselves look consistent and as if they exist in the same space. The drawings look solid as a whole. However, always draw through your forms and pay attention to the shadows being casted: they should stick to the forms they are casted upon, not the forms that cast them.

Generally, I recommend that you focus a bit more on sausages with ellipses and curves in your warm-ups, maybe do them a couple times to start to get the hang of them. The same thing applies to boxes.

Actually, I'm a bit unsure if you've completed Lesson 1 and 250 boxes challenge prior to completing Lesson 2, as your sketchbook doesn't have them; I will assume that you did and provide next steps based on that, but if you didn't, I would recommend that you start from the beginning (Lessons 0 and 1), so that you're not missing out on a lot of essential info.
