Hi there I'll be handling your lesson 2 critique.

You're making good progress towards understanding all the concepts introduced in this lesson, below I'll be listing some improvements you can make in your future attempts.

  • Your arrows are off to a decent start, I just have 2 quick notes for you here. The first being that you want to remember that you can foreshorten the negative space between the curves of the arrow as well to really sell the illusion of the arrow moving through 3D space. You can read about the concept here. The second being that you don't overlap your lines in curves as much as you should at times, this results in your arrows bulging and stretching rather than flowing smoothly, more on that here.

  • In the organic forms with contours exercises I'm glad to see you're shifting the degree of your contours along with the forms. Again just have 2 notes for you here, the first being that when you draw the small ellipse on the end you want to make sure it's just on ends facing the viewer, the second being that you did go a bit too complex with your sausages. When constructing a simple sausage you want both ends of your form to be roughly the same size, and avoid any pinching, bloating, or stretching along the form itself. You can read more about what qualifies as a simple sausage here.

  • I can see your brain wrestling with the concepts in the textures exercises which is understandable seeing how it's a difficult exercise. You do have the tendency to focus on outlines and negative space rather than considering how cast shadows would be created by forms along the texture, this makes it difficult for you to create gradients and imply detail. You can read more about the importance of why we're trying to focus on cast shadows here. This is something that takes a lot of practice and we don't expect you to nail it the first time around, you did get closer in some of your attempts than others, so just keep practicing and you'll find it becomes more natural and you'll develop a better eye for how your textures would behave.

  • The forms intersections exercise is a bit similar in the sense that it's meant to be an introduction to a difficult concept and not one we expect you to fully grasp just yet, right now the goal of this exercise is 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. It's good that you attempted to draw the intersections even if you don't fully understand how they intersect or if they'r correct or not, the goal is to just get you thinking about the fact that they DO intersect in 3D space and as you build your understanding of 3D space you'll find it easier to imagine them doing so, thus making it easier for you to draw them when necessary. We will be going over them more in the upcoming material in some more natural examples, this is a case where such simplified forms actually makes it trickier to imagine in some ways. If you do want to see some examples of this your best would probably be to use something like Blender or another 3D modeling software to intersect some basic forms together, but keep in mind this was meant to be from imagination and we'll be using some references later on

  • Lastly in your organic intersections you drew your forms too complex and it resulted in things appearing less solid than they could. In this exercise keeping forms simple is actually very beneficial because we can wrap each form around one another in a clearer fashion, by doing so we can also use a consistent light source to build our understanding of shadows. For the most part your shadows aren't actually casting on to the forms below and instead are hugging the forms they're being created by. In the future if you simplify your forms and focus on how they would lay on top of one another you'll build up an understanding of the 3D space and shadows you're working with, this will transfer a lot smoother when going to more complex forms later than trying to make them complex now.

Overall while you have some things to work on this was a solid submission, I don't believe it's necessary for you to redo any exercises so I'll be marking your submission as complete. With that said you should redo all of these exercises as well as previous ones in your warm ups to help build up your mileage and understanding. Remember that each lesson builds on each other so a set of strong foundational skills will help in everything you do.

Good work so far and good luck in lesson 3.
