No worries, thank you for your patience.

You're making good progress towards understanding the concepts introduced in this lesson, below I'll be listing some things that will hopefully help you in your future attempts at these exercises.

• Your arrows are off to a good start but do have some wobbling occurring. As long as you remember that we want to be drawing every mark we make confidently this will improve in no time. There are a few spots where your arrows widen/narrow suddenly, we want to try and have their width change consistently to avoid giving the impression that they're stretching which hurts their solidity. I'd like you to experiment with foreshortening a bit more when trying this exercise again in the future. 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 arrow moving through 3D space as you can see demonstrated here.

• You're close to keeping your organic forms with contours simple, but some do a get bit complex at times. Our goal when creating these forms is to have both ends be the same size and to avoid any pinching, bloating, or stretching along the form's length as discussed here. When it comes to your contours you're not always drawing through your ellipses (remember we want to draw them them all) and you have some more wobbling occurring, this shows me that you're most likely focused on accuracy over your line confidence. We want to try and reverse that for now because as long as we draw confidently our lines will become more accurate with mileage, if you need to break the boundaries you've established for now to keep your lines smooth then don't be afraid to do so. I'd like you to try and shift the degree of your contours when trying this exercise again as well. 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 the 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.

• If you feel like you don't fully grasp form intersections just yet don't worry, you're on the right track but right now 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 mostly solid here, the major issues are previously mentioned ones (line confidence, not drawing through your ellipses).

• Just a few quick notes for your organic intersections and we'll wrap this critique up. I'd like you to draw through all of your forms when doing this exercise, much like how we drew through all of our boxes we can do so here for the same reason, drawing through our forms helps us develop a better understanding of how all these forms rest in the 3D space we're trying to create. When drawing your contours curves try to push them further so that they hook back into the form as demonstrated here. You're showing that your sense of 3D space is growing as your forms start to wrap around one another believably which is great, you're off to a good start with your shadows as well just don't be afraid to experiment with pushing them further and trying different lighting positions.

Overall this was a solid submission, you have some things to work on but I have no doubt as long as you work on drawing confidently and keep the advice above in mind you'll improve with more mileage. I'll be moving you on to the next lesson and marking your submission as complete.

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