Seems there's only 11 images in the album from our end (may be a privacy setting, I haven't used flickr so I'm unsure), that being said if I go to your profile I can see the rest of the images so I'll just work around it that way.

You're making progress towards understanding the concepts introduced in this lesson and hopefully this critique will help you in your future attempts.

• Starting off in the arrows section your lines are looking smoothly and confidently drawn. There are spots where your arrows bulge/narrow suddenly, this is an issue because it gives the impression that your arrows are stretching which hurts their solidity. Remember that as our arrows move closer to the viewer we want them to widen consistently. It's good to see that you're trying to implement line weight, just remember that you want to keep your applications subtle and you'll become consistent with mileage. here are some things to look out for when applying it. At times you don't overlap your edges when you should, this results in your arrows flattening out as you can see here. I'd like you to experiment more with foreshortening in your future attempts, by utilizing it in both the arrows themselves as well as the negative space between their curves we can create a stronger illusion of an object moving through 3D space as demonstrated here.

• Moving into the organic forms with contours exercise you're doing a good job keeping your forms simple, plenty of people tend to over-complicate them. You're keeping your line work confident here which is great, if you feel uncomfortable working with contours still don't stress with more mileage it'll become more natural. Speaking of contours I'd like you to try and shift the degree of your contours more. The degree of a contour line basically represents the orientation of that cross-section in space, relative to the viewer, and as we slide along the sausage form, the cross section is either going to open up (allowing us to see more of it) or turn away from the viewer (allowing us to see less), as shown here.

• In the texture exercises (more so in your dissections) you're focusing largely on outlines and negative space rather than cast shadows created by forms along the texture itself. This makes it difficult to create gradients with implied information which we could then use to create focal points in more complex pieces, by doing so we can prevent our viewers from being visually overwhelmed with too much detail. For more on the importance of focusing on cast shadows read here. I'd also like to quickly direct you to this image which shows that when we're working with thin line like textures if we outline and fill the shadow we will create a much more dynamic texture than simply drawing lines.

• It's quite common for people to feel like they don't fully grasp the form intersections exercise, if you feel like you may fall into this category try not to stress too much. This exercise is just meant to get students to start thinking about how their forms relate to one another in 3D space, and how to define those relationships on the page. We'll be going over them more in the upcoming lessons.Your forms are looking quite solid here and they believably appear to belong in the same cohesive 3D space, good work.

• While wrapping up your submission with the organic intersections exercise you show that you need a bit more time becoming comfortable with thinking of how these forms interact in 3D space and how they'd wrap around one another. Currently you're mostly drawing your forms over one another instead of wrapping them around the forms below.You're keeping your forms simple and easy to work with which is a good strategy to help produce good results. Your shadows are hugging the form creating them at times rather than being cast on to another surface believably. It appears like your shadows aren't following a consistent light source, I recommend pushing your light source to the top left or right corner of the page to start with, it's easier than working with a light directly above your form pile.

Overall this was a solid submission, while you may have some things to work on I have no doubt you will improve with more mileage. I'll be marking your submission as complete and move you on to the next lesson.

Keep practicing previous exercises as warm ups and good luck in lesson 3!
