Firstly, Congratulations on completing the lesson!

Your biggest strength is definitely your linework. It's very clean and confident.

===

Excellent work with making the arrows go far back into space.

But cap off the arrows at the back lol. Never leave an open end. It quickly destroys solidity.

==

The degree of your ellipses changes nicely in the organic forms with contour lines/ellipses exercise. You seem to have a pretty good understanding of how they flow through space.

You could try to ghost the ellipses a bit more.

Regarding a (very) few of your ellipses, it seems you're trying to correct their positions in your second pass - i.e. you're (sometimes) tracking your ellipse as you draw it. Avoid doing so. A tip that helped me especially was trying to execute the second pass exactly the same as the first. Try work your arm muscles in the exact same manner as in the first pass.

This will also help with the occasional wobbliness you have.

("I did a horrible job on textures but at least I tried doing it for once."

Honestly I also found the textures exercise extremely tedious and had to force myself to slough through it lol)

The texture analysis exercise, well, you're in the same position I was. You're direct studies are really good, but you're way too timid with your shadows when trying to make the texture gradient. Make them a lot bolder and deeper. Remind yourself, the entire left part is in darkness, and the right part is where light is blasting out. Imagining a torch held at the right side helped me personally.

Especially for the tree bark, the part thats at the left should be in the middle.

You should check the critique I got on my post regarding texture analysis if you wanna. It was really well worded. I won't tell you to redo the texture analysis exercise, but do take a look at the aforementioned.

===

Your dissections exercise is really well done. Again, the shadows at the ends should be bolder, but otherwise, and especially the animal skin/scales ones are amazing.

A general tip after looking at the sponge one, but the shadows for anything with distinct holes are almost always crescent shaped if the light is coming at an angle (as in our case for the sausages).

For the bricks, again, something I myself drew similar to yours, make them much more curved when wrapping around a sausage/any round form. Compare it to Uncomfortable's demo example on the exercise page.

===

For the inorganic intersections, I have no right to speak on the intersections themselves, but good job on the rest. Again, your clean linework really shines here - they all look very solid and in the same space. Your spheres are also very good.

==

The flattened sausages in organic intersections are very well done.

One thing is that, for something slagging on the ground, the shadow should be visible on the side that faces the viewer. For example, the shadow being on both sides of the bottom left flat sausage on the second page rather kills it solidity, because it's impossible without multiple light sources. The part of the shadow to the left of that sausage wouldn't be visible as long as there's a single light source. Sorry if the wording is confusing.

Basically, the shadow on the bottom middle big sausage on the first page is fine, but the one on the bottom left flattened sausage on the second page kills the solidity.

==

Overall I'd say you did really well. I pointed out the small errors here and there that I saw. As you said, the texture analysis exercise is pretty much the only one you should pay more attention to. I'd recommend you look at a few other people's work on this exercise (hopefully it helps you as much as it did me). Try doing a texture analysis or two if you're feeling motivated enough. This is still optional though as long as you know what you should be doing (there will be opportunities to apply texture in the future lessons)

(This is not very good but illustrates the point about timid shadows:

Sorry if the English was janky at points.

All the best with your art journey!
