Hi there Razgriz! Great job on finishing this lesson. Here's some feedback:

Arrows:

For your arrows, make sure to not hatch. Make one confident line and don't correct it. Adding lineweight is fine, but don't do it in little bits. Ghost this lineweight line also. I say this because sometime the lines are a little wobbly. With hatching too, make sure to not just move your hand back and forth and do all the lines in one go, but focus on each invidivual line when hatching! Your confidence on the big lines improves a lot in the second page. Keep it up!

Organic Forms:

Your organic forms look pretty good! Do make sure that the axes are kind of in the middle of the ellipse, and they don't drift to the top or bottom. Also, as the ellipses change their orientation, they become narrower and wider. Your ellipses don't really change in width this much, except for one on the left, so this is something you could improve. Also make sure to draw through your ellipses 2-3 times. Don't draw them just once, or go over them 4 times, like I see in some of them.

Your C's hook nicely around the forms on the second page, but I would watch out for this: Demo And also keep in mind the changing of degree of these, even though they aren't ellipses.

Texture analysis:

For your texture analysis, I can really see that you put a lot of time into these, but it's not necessary to draw every individual feather or scale! Instead, this exercise focuses on creating a transition from dense to sparse marks. This wage, the left of the texture is fully black, and the right is fully white. I think you struggle with messyness a little bit on this one, as some of your lines are hatchy instead of fluid and confident. I think that is in part because you draw every individual element, which is too much work. I would really like you to redo this exercise and create a very clear transition from full black to full white.

Dissection:

Your dissections suffer from the same issue of drawing every single detail, and you hatch on many of them. Don't hatch! Remember, you're not supposed to represent actual light, but this is about drawing the 3D differences in the texture. So if something is darker, don't hatch it to represent that. Keep it light, but only indicate the 3D differences. Some of your shapes are empty also. If you fill these in with these improvements, that could help a lot.

Intersections:

You didn't intersect your boxes on the first page, and I think this made you struggle more with the rest of the exercise, because it only gets more complicated from there. You did great on the ball intersecting with the box on the bottom left of the page marked as "4" though! This one very clearly follows the curve of the ball. The right edge of that ball, though, doesn't make the same amount of sense. When intersecting these forms, it can help to not just draw the side you see, but to draw through the forms in a sort of "x-ray vision" so that you can see the whole intersection even in the area that is covered. But when it comes to boxes, you need to make sure that the intersections follow the box's perspective, and don't go into a different direction. I think if you redo this page and this time really pay attention and look at examples, it will go much better. Don't rush it!

Organic Intersections:

This one is really good! Apart from previous issues with somewhat wobbly lines and correcting your lines (don't correct them), you can clearly see where the shapes are, which ones are top. There's just one thing, which is that they don't all feel like they have the right weight to them - or that it's not realistic for them to be in this position. I'd expect them to roll off or fall down. Take a look at this to see what I'm talking about.

Conclusion:

This is a very great start! But I don't think you took the time for all exercises, and some of them are unfinished. I'd like you to:

1) Redo one texture analysis. This time, pay attention to the 3D effect instead of each individual element. Create a very clear transition from dense (full black) to sparse (full white).

2) Finish the dissections on your page that are empty right now. Make a clearer transition from dense to sparse again and don't draw every individual element. Also make sure to not rush it, don't hatch, and think well about each mark you make.

3) Add more boxes to your first page of Form Intersections so that there's more overlap, and then draw the intersections they have. You can also choose to redo this page from the start.

4) Redo one page of intersections that mixes boxes and other shapes.

Make these, send them to me and I will look at them and then mark your stuff as complete!
