sorry for the shitty lighting, I'm currently moving and don't have everything set up yet

Hello I’ll be handling the critique for your 25 wheel challenge.
-Starting with the structure of your wheels I noticed that in many cases you’ve laid a simple straight cylinder for them, it is important that you add a subtle bump in the midsection, this will make the wheel look inflated, which is an important aspect as they are filled with air and aren't as rigid as they may seem.
When I was working on this challenge I do remember looking at some wheels that looked completely flat, but regardless, always try to add a larger ellipse to imply the presence of this bump.
-When it comes to the other structural elements like the spokes/rims you do seem to be implying the presence of their side planes to make them look more solid. There are a few instances wher you don’t do this and there are others when you rely on form shading,
This form shading, where you're making a surface lighter or darker based on its orientation in space - should not be included in our drawings for this course. Instead, you'd be drawing the outlines for the entire 3D structure, defining the edge between the side plane and the front/outward face, and reserving filled areas of solid black only for cast shadows.
-This challenge serves to reminds us of some of the things we learned in lesson 2 texture section. In your case I think we are getting some mixed results, there are definetely some cases where you have decided to draw the texture details explicitly, a really good example would be number wheel number 7 and number 15, where all of the textural shapes edges are clearly outlined.
While doing this is not necessarily bad, as it can help you to be more aware of how this forms wrap around a surface, this kind of small details tend to pile up and drawing them explicitly results in a lot of visual noise and clutter. That’s why we decide to draw them implicitly using cast shadows.
When you draw them keep in mind the form casting the shadow and also take some time to design its shape, and think about how it wraps around the surface it is falling on.
Here is a diagram that actually explains this point pretty well https://imgur.io/SEwsEfO , on the top you have the textural form with its outline and planes drawn explicitly, and below them on the second row you have the side planes filled with black which falls under the category of form shading, on the right you have the cast shadow example hich is the correct one.
-On the other hand you are also making use of simple lines to draw the texture of the tyre. It gets trickier here because we'll often mistakenly think about the grooves themselves as being the textural forms in question - but that is not the case. Grooves, like any other holes (like in a sponge texture) are not forms - they're negative space, empty space, and the forms in question are actually the walls surrounding them. This diagram helps to explain the distinction. https://imgur.io/SCnATRK
Okayy I’ll go ahead and mark this lesson as complete, though make sure to review the texture section on lesson 2 if you need a reminder.
You're almost done just one more lesson!!
Next Steps:

Thank you so much for the detailed critique, it is so helpful to have someone else point out your mistakes and explain how to do it better, I will keep the mentioned points in mind.
I really struggle with texture, so your tips are super appreciated. I will look at lesson 2 again and maybe redo some exercises. Is there a way to get critique on exercises without doing the full lesson?
Thank you again

unfortunately there is not, but I don't think it may be necessary to have them reviewed, besides texture is kind of a secondary aim when it comes to these exercises.
Anyways good luck with the next lesson

You can post individual exercises in the lesson 2 channel on Discord and ask for feedback on them, if you want. It's not guaranteed that you will get a response though.

It's also more than that - it's a hand-picked recommendation of something I've used myself. If you're interested, here is a full list.
Drawabox-Tested Fineliners (Pack of 10, $17.50 USD)
Let's be real here for a second: fineliners can get pricey. It varies from brand to brand, store to store, and country to country, but good fineliners like the Staedtler Pigment Liner (my personal brand favourite) can cost an arm and a leg. I remember finding them being sold individually at a Michael's for $4-$5 each. That's highway robbery right there.
Now, we're not a big company ourselves or anything, but we have been in a position to periodically import large batches of pens that we've sourced ourselves - using the wholesale route to keep costs down, and then to split the savings between getting pens to you for cheaper, and setting some aside to one day produce our own.
These pens are each hand-tested (on a little card we include in the package) to avoid sending out any duds (another problem with pens sold in stores). We also checked out a handful of different options before settling on this supplier - mainly looking for pens that were as close to the Staedtler Pigment Liner. If I'm being honest, I think these might even perform a little better, at least for our use case in this course.
We've also tested their longevity. We've found that if we're reasonably gentle with them, we can get through all of Lesson 1, and halfway through the box challenge. We actually had ScyllaStew test them while recording realtime videos of her working through the lesson work, which you can check out here, along with a variety of reviews of other brands.
Now, I will say this - we're only really in a position to make this an attractive offer for those in the continental United States (where we can offer shipping for free). We do ship internationally, but between the shipping prices and shipping times, it's probably not the best offer you can find - though this may depend. We also straight up can't ship to the UK, thanks to some fairly new restrictions they've put into place relating to their Brexit transition. I know that's a bummer - I'm Canadian myself - but hopefully one day we can expand things more meaningfully to the rest of the world.
