Hi Baozi, I'm gonna go over your submission,

Starting out by your organic arrows, I really like how you are making them flow confidently through space, remember that you can make a more solid illusion of the arrows getting closer by making them bigger as they get closer and making the space in between turns smaller as they get further away; you are already doing this but sometimes you are mixing them a bit, so try to exagerate this and have fun with it! Also, I'm seeing that you started trying to add line weight focusing on confidence, though then you started doing a slow wobbly line. Keep striving to apply your line weight confidently by ghosting them, you will get better at accuracy with millage, so push through!

Moving on to your organic forms, they are very close to the characteristics of the simple sausage, though try to make both ends more rounder and the same size! On your contour curves, you are doing a good job on them, however, I would advice you push their roundness a little more since they are falling a little flat and this sausages are round. One thing that you can do to sell a better illusion of depth is changing the degrees of your ellipses- The ellipses and contour cuves of this exercise represent how the cross sections along the sausage face towards de viewer, if they start moving towards the viewer, we'll be able to see more of them (higher degree), though if it starts moving away from the viewer, we'll see less (lower degree). Here is a diagram that explains it more visually.

On to your textures, overall you are doing a good job at them, this is a difficult exercise. However there are a few things I want to point out so you keep on the right track.

• First, you are almost doing the perfect job, because although you are using cast shadows to implicitly showing the viewer how that texture is feels (because remember that that's why we use texture here, not to create pretty pictures), you are still sometimes falling into using lines to describe those textures. I'd recommend you go back to the implicit vs explicit video on the lesson, where Uncomfy explains why is it important that we don't just jump into exactly everything we see (which you are not doing, don't worry).

• On the same note, the reasons we use a gradient from dark to light on the dissections is so we can use cast shadows, though I'm seing that you've use one in cases like your textured glass and your pelican back, in which you did a great job!

Your form intersections look pretty solid, the major thing that I'm seeing is that you are sometimes getting a little messy with the line weight, remember that is supposed to be added subtly and as a super imposed line that we ghost beforehand (like every mark we put down in this course; it should be ghosted), so keep that in mind moving forward! Also, you can use paint 3d after you are done with your exercises, to check how the intersections really are!

So, on your organic intersections you are doing a good job making them sit in top of each other, though you are doing a lot of scratchy lines, remember that our priority with every line is making them as confident as we can, so always ghost your lines and strive for that. Also, when you are doing cast shadows, I'd recommend you get a brush pen to fill them in with black, though if you cannot get one, you should take your time to slowly fill them up as solid as you can, since leaving them how they are now, they are too scratchy and end up fighting against what you did on the exercise.

Overall, you did a solid work on this lesson, remember to ghost all of your lines though. I'm gonna go ahead and mark it as completed! Keep it up.
