Hello Rafellus!, I am Doctormein And I'll be critiquing your lesson 4 submission for today.

Starting with your organic form, First thing i would like to point out is that, The lesson asked for 2 Contour curves variant. Right now you're having 1 page of ellipses variant and 1 of contour, Don't forget to pay attention to the instruction!

Now, Regarding the construction of organic form (contour curve variant.) themselves, Their gesture looks pretty great, But the shape of them is a bit elongated, make sure to try your best and draw the sausages as simple as possible https://drawabox.com/lesson/2/5/simplesausage unnecessary complexities will only make the exercise harder and distract you from the main point.

For the contour curves Don't forget that the concept of ellipses variant still apply here, The curves will naturally become thinner or wider, Their curves will never be exactly the same degree Think of a coin, If you are looking at the front side of the coin it will be perceived as a circle, As you slowly get closer to the side however, The coin will slowly become thinner and thinner until it nearly become one single line. https://media.discordapp.net/attachments/368871002584907776/867744968432549928/QTEqgJa_1.png?width=618&height=601 (An image showing different degree of contour curves, This might prove to be useful to you!)

In some of your contour curves, The curves is a bit far off from being perceived as aligned with the minor axis, It might be a good idea to also practice that too https://drawabox.com/lesson/2/5/alignment

Insects,Arachnids,Crustaceans Main Construction

The main takeaway of your assignment right now is, Your drawing doesn't adhere to the illusion of 3d form, For example your Dynastes Hercules, His shell almost felt like it's floating, https://drawabox.com/lesson/4/7/shrimp if we take a look at Uncomfortable "Shrimp informal demo construction" This is very important, Make sure to check out a lot of informal demo! They're more up to date with what the course wanted to teach you.

We can clearly see Mr.Uncomfortable is adhering to his own Belief that the form he's drawing are 3D and not a flat 2d shape, and proceed to add the shell accordingly (Curve the shell accordingly to his belief that the forms are 3D.) Don't ignore the base form, Those organic forms, circle you've drawn are the Foundation of your construction, Anything that comes afterward this basic form must be added on top of this basic form and curves or follow the form accordingly. I recommend if you're struggling, It would be a great idea to follow along the informal demos, It'll certainly help you out a great deal when focusing on your own construction.

Secondly, When constructing something, Try your best not to cut into the original or the base form, Although it is possible to cut into the form https://imgur.com/VdwbRuU (How to subtract form correctly from uncomfortable) It's usually more trouble than it's worth

Thirdly, Although the legs you've drawn with Organic forms are fine on their own, It would be better if you could incoporate Additional masses to further refine its silhouettes https://imgur.com/7b9rc9e (An image showing how to add additional form to further refine the silhouettes) https://cdn.discordapp.com/attachments/368871234269741066/948218540605976576/IMG_1592.png (An image showing how you should be adding the additional form, This apply from this lesson to lesson 5 too.) https://imgur.com/X4tx6KB (Head construction by uncomfy)

Regarding Line quality , ETC

Your line quality right now felt a bit chicken scratchy and hesitant, Remember, we're not here to sketch, Every form every lines and every additional masses must be added with confident while adhering to your BELIEF of 3D form , Even if the line you drew is not exactly the line you wanted, Remember to always leave the line as it is, Don't try to change or do anything to them, As long as you're having clear forethought before drawing them and trying your best then it's good enough https://drawabox.com/lesson/2/3/learningtechnique

And finally

I think it's a good idea to draw only 1 drawing per page, Because this will allow you to draw bigger, Which will certainly help your brain to better understand the spatial problem being presented, (And it would be easier to count too!)

I think that roughly conclude this critique, I can provide you with demo if you wish so (Although it won't be as good as uncomfortable one)

So now i'll be moving to conclusion
