I drew some of them with the ellipse guide, some hand free, the bigger ones are all hand freed (it shows ahah) , as for the smaller the only ones drawn with the ellipse guide are: the first 6, the 12th and 13th and the 16th
next time I'll buy a bigger ellipse guide for sure.

Hello I’ll be handling the critique for your 25 wheel challenge.
-Starting by the structural aspect of your wheels, I think you are aware of the bump that is present on the middle of the wheels that helps them to look inflated. There are certainly a few cases where it seems that the wheel is a straight cylinder like on wheel 14, I have to acknowledge that adding this ellipse can be quite tricky if you are freehanding, so I would have recommended you to stick to the ellipse guide.
When it comes to the other structural aspect of your wheels, which are the rims and spokes I think you could do a much better job. RIght now it seems that you are drawing them as simple straight lines, so it is important to define their outward faces as well as the sides planes. I did notice some examples where you filled those side planes with black, but keep in mind that areas of black should be reserved for cast shadows only, this falls more on the area of form shading. And this leads to the other aspect of this challenge.
This challenge serves as a reminder of the concepts we learned in the lesson 2 texture section, most students by this point will have forgotten most of it, so don’t worry if that’s the case for you as it is completely expected.
Taking a look at your wheels I do notice that most of the textures of the tyres are explicitly drawn.
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
(just like you did on the spokes), and on the right you have the cast shadow example which is the correct one.
There are a few cases where you seem to be moving in the right direction like on wheel 19, where it seems that you are more deliberate when it comes to drawing those cast shadows.
But most of the time you are actually using lines when the texture consist of shallower grooves, it is a common mistake to think of the grooves as being the forms themselves, but this is no the case, just 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 .
My main recommendation for you is to first outline the shadow shape while thinking about the form casting it and how it wraps around the surface it is falling on, once you’ve done that you can fill it with black, this will help you to form a better understanding of how all of this comes together. Here you can see a good example https://imgur.com/oAx2pRD .
Okayy so that should be about everything I wanted to talk about, while there were some mistakes I won’t be asking for any kind of revision as it is completely expected of students to make those mistakes.
I’ll just go ahead and mark this lesson as complete and let you move on to the last lesson. Good luck!!!
Next Steps:
lesson 7
Hello beckerito, thanks again for your valuable critique, I did have a hard time with the texture part, it is as you said I forgot a lot about it, for the next lesson I'll be sure to practice it and I'll buy a bigger ellipse guide too.
When I'll be back from vacation I'll be sure to practice following along your suggestions and the links you provided.
Thanks again for taking the time to critique my submission!
A lot of my students use these. The last time I used them was when I was in high school, and at the time I felt that they dried out pretty quickly, though I may have simply been mishandling them. As with all pens, make sure you're capping them when they're not in use, and try not to apply too much pressure. You really only need to be touching the page, not mashing your pen into it.
On the flipside, they tend to be on the cheaper side of things, so if you're just getting started (beginners tend to have poor pressure control), you're probably going to destroy a few pens - going cheaper in that case is not a bad idea.
In terms of line weight, the sizes are pretty weird. 08 corresponds to 0.5mm, which is what I recommend for the drawabox lessons, whereas 05 corresponds to 0.45mm, which is pretty close and can also be used.
