Hello Lefebul! About the demo thing, some content on the lessons isn't fully updated and has some old stuff, like what you saw on some of the lesson 5 demos. In these cases comfy still includes the older demos because he thinks they can still be useful, but you should ignore everything that contradicts anything comfy has previously said, specially text has priority over the videos.

So for example limbs in general should be approached with sausage forms and not cylinders or 2d shapes like he does on the wolf demo.

Now into your critique!

Starting with your organic intersections they feel super solid! You are drawing all forms confidently, sticking to simple forms only, and the shadows are believable as well. The only thing here is that some of the forms you drew feel like they aren't very stable. Try to imagine whenever you are adding a new form as if you were throwing a new of those sausages and it acting like a water baloon. Some of the ones you drew would be affected by gravity and finally fell and changed position, so try to keep that in mind on future attempts.

About the animal drawings, honestly you've done a pretty good job overall! The animals in general feel pretty general and believable, and you are approaching very well the additional forms.

The only things I've seen is that your approach varies across the drawings. For example on the otter demo you are approaching the legs with 2d shapes, which is something you already corrected over the next drawings. As I already explained before they should be approached like you did on the next ones, using sausage forms and connecting them with intersections.

In a similar way sometimes you draw the limbs as stretched ellipses instead of simple sausage forms, which makes them a bit stiffer. Here's an example on the bear you drew.

And lastly on the legs as well, sometimes you drew two separated sausages that didn't overlap and then added the connection after. Try to always approach them like the others on which you overlapped both sausages and then drew the intersection of them. If you want to add more mass you can do it with additional forms, but always after. Here's the example.

Lastly on additional forms like I said you overall did a pretty good job, but there are a few cases on which you don't wrap them around the other side of the form. Here's an example on the cow. I drew around the other side of the form so you could understand what I was trying to show, but it isn't necessary to draw it on your drawings of course as long as you are aware of it. As you can see I added it on 2 forms as well. Whenenver a form gets too complex, (like bumpy on one side and flatter on the other) make sure you break it down in several forms. It's important that all the forms you draw on these drawabox exercises are simple so you can add complexity step by step.

On the suggestion you said I think you made a good step, but I wouldn't add the last part with a ball. Try to always build everything using additional forms and wrapping them around the forms you've already built. Heres how I would have done it.

Last thing I wanted to talk about is textures. You've largely done a pretty good job on them with good observation skills and focusing on drawing cast shadows without outlining forms. The only thing I want to comment on is your use on the silhouette on the forms. Whenenver you are adding texture on the silhouette you don't have to draw fur for example all over it. Just adding a few chunks of fur already gives it the affect of being a fur-like texture, so make sure you don't overdo it.

I've also seen you sometimes repeat a lot the same shapes, try to give them more variety to the silhouettes specially. Here's one example with the bear.

Overall like I've said you've done a pretty good job so I'll mark this as complete. Good luck on the cylinder challenge and keep up the good work!

I'm just a beginner so I'm not here to critique your drawing, sorry for making you think you'll have some criticism

anw your drawings are very inspiring, im looking forward to achieve your level: >>
