This exercise is less about getting organic forms to actually cut into one another, and more about how they can be piled on top of one another in a way that feels convincing. It requires a grasp of the weight of these sausage forms, and how they might slump and sag where that weight is not supported.
Keep your forms simple, and try to picture them as being a bunch of water balloons that you're trying to set in a pile.

To start with, draw a simple organic form. Since we're going to be dealing with a lot of them, the complexity of each individual form is not particularly important. It's generally best to stick to something simple, like a sausage form.
)
Next, just like in our organic forms with contour curves, and even in our dissections, we add contour lines to give the form volume and form. As you complete this step, think about what it is you're doing - you're not just drawing lines on a page. You're imbuing a flat shape with volume, with weight, with solid form. It's no longer just a 2D shape, but a 3D object that can be lifted, moved, thrown and dropped. If you pick it up from one end, it will dangle. If you hold it from its middle, it will sag on both sides.
Don't move ahead until you can feel it in your mind, that this form has real weight to it.
)
Now we're going to test this idea. Imagine that you had another dangly sausage form, and that you dropped it on top of the first. Consider how it would fall, how it would be held up in one place, and sag in others. Consider how it would conform to the mass beneath it.
)
All there is to do afterwards is repeat the process. You can drop more organic forms on top, or you can play with wrapping them around each other, or jamming them into one another. It's completely up to you.
The important thing is what I've stressed thus far - you're not pasting flat shapes on top of each other, you're dealing with solid forms that cannot occupy the same space. So, in order to wedge them against one another, one has to displace the other.
Much of what we tackled in the form intersections is at play here as well - the only difference is that our forms are more malleable and flexible. When two of these forms intersect, they displace each other as I mentioned, but you still experience a dominance of one form over another, and that dominance is still handed off between them at different points in space.
This kind of exercise can be quite calming, once you get the rhythm and the sense of form and mass. Once that clicks, it's just a matter of dropping form after form after form. In the long run, you will also find this exercise to come up when you start dealing with topics such as drawing insects, or drawing animals, where we often need to add additional masses in a way that doesn't just feel like we're pasting stickers on top of our construction. Every form we add needs to somehow relate solidly and consistently to that which is already there in order for the whole thing to maintain its believability and sense of solidity.
)
Try to stick to really simple sausage forms, as shown in the instructions here. Stay away from forms that have swelling or tapering through their lengths, or forms that are too long and snakelike. Simple sausages with consistent widths through their lengths is what you want.
)
When dealing with the shadows cast by our forms, we need to remember that these shadows are being cast and projected onto the surfaces that exist beneath the form - whether that surface is directly underneath or miles away, whether it's flat and simple or curving in some awkward manner. The shadow itself warps itself to the surface it falls upon. A frequent mistake is to have the shadow adhere too closely to the form casting it, resulting in some illusion-breaking shadow play.
Since one page should contain only one 'pile' of forms, this is the same as the last step shown above.

Despite their age, Marshall Vandruff's videos on Linear Perspective are some of the best lectures on all the ins and outs of perspective, and as an instructor, he is highly respected across the board. He goes into a lot of the intricacies that I don't touch on in much depth (at least, not if I can help it).
On top of being some of the best, his lectures are also among the most accessible, at the full 8 hour set for $12.00. There's literally no reason not to grab them.
Having your work reviewed by others is critical, as those who are just starting out aren't in a position to properly judge their own work, and won't be for quite some time. Don't be afraid to show your struggles - it's by analyzing your mistakes that we can help you grow. Perfect homework is not what we're looking for; we just need it to be complete.
There are currently two places you can get your work critiqued by the community - Reddit and our Discord Chat Server.
Both of these are completely free.
If you are interested in receiving extra help, I critique the work of those who support Drawabox on Patreon.
All of these private critiques are done through reddit, in specific threads where students post their work as a comment, including a link to their work (often hosted on Imgur, though most image hosts are okay).
My requirements are more strict than the free community critiques:
The minimum pledge for this lesson is $5.00/month. The orange button above will take you to the reddit thread for this lesson, you can post a link to your work there and I'll be notified. Once I catch the submission, I'll add it to this backlog spreadsheet.
Pledges are collected at the beginning of the following month, but you may start submitting your work immediately. If you're a new patron, I'll be reaching out to your shortly to collect your reddit username.
