Arrows

Arrows are looking pretty good in general good job! There are still a few places places where the arrow should have grown but it didn't, like on the last 2 folds on this arrow, which are of similar size. But overall they give a pretty good sense of depth.

The main thing I notice about them is their lineweight. When adding lineweight to the overlaps, do it with a superimposed confident line. Yours are a bit wobbly, so don't forget that here as well you should be focusing on confidence. Shading looks a little bit rushed too, so don't forget to take your time with each line there as well.

Organic forms

Organic forms are almost there, but they are mostly not the forms we're aiming for. If you take a look at this image, you'll find most of the forms you've drawn on the picture to be on the mistake labelled as "continually widens like an ellipse".

Here are some examples over your work to make it a bit more clear.

You're focusing on confidence on them, which is great, but the linework itself hints me you might be rushing them a bit. Take care to make each one of those as best as you can, don't forget to ghost as much as you need to do so.

Contour curves are a little bit too shallow, take a look at this to see what I'm talking about.

And the ellipses on your sausages are a bit misalligned, it's pretty hard, but remember the ellipse exercise and do your best!

Textures

Good job on textures overall, but it looks like you might be rushing them a bit. Remember that you should be looking 90% of the time at the reference¡ and only the other 10% drawing. This exercise is very hard and boring so don't hesitate to take a break if you feel you're starting to rush, take it easy.

On the dissections, make sure you're following the form where adding the texture. Here's an example where you made the texture a bit flat.

Lastly, in general to help you with the observation thing, you can use this approach with all the shadows on these exercises. This will make you stop relying on lines and will make the exercise easier.

Form intersections

Here you have a few issues. You fixed some of them through the set, but some are still there:

-First is repeating lines. You started doing it less by the end of the set, but you're still doing it. Don't forget that no matter how off a line is you shouldn't repeat it. Keep going as if it had been correct.

-Second is that the boxes have pretty similar orientations. Try to play a bit more with them. Take a look at this to see all the orientations you can make with a box.

-Lines are overshooting a bit too much in general, check you're ghosting as much as you need on each line, don't rush it.

And same with the hatching. It has fraying on both ends in some instances, be careful with that as well.

Organic intersections

Here you're in the right track, but a few things to comment on as well:

-Main problem is that you got some sausages that are floating. Every sausage on this exercise should be solid, and shouldn't look like it's about to fall .

To help you with it, you can approach the sausages like this.

Here's a demo I made to hopefully make it a bit more clear. I recommend rewatching uncomfortable's demo as well.

-In some instances your sausages are a little bit squished. Don't forget that the sausages on this exercise should still be the simple forms of the previous exercises. Some examples.

-And lastly, the shadows are a little bit jagged. You can use the approach I mentioned on the texture section for this exercise as well. First draw the shadow shape, then fill it.

Before moving on I wanna make sure you understood the stuff I mentioned, because it's a lot to take in. So i'm going to ask you to do:

-2 pages of organic forms, one with contour ellipses and other with contour curves.

-1 page of organic intersections.

And before doing the organic intersections page I want you to follow along uncomfortable's demo. Good luck and keep up the good work!
