Hi TotalTempest! I'll be reviewing your work. Let's see:

Organic Intersections:

The line is a bit wobbly, and the excessive lineweight does not help. Remember to apply that only on sections that intersect each other, to clarify which form is on top of which. The sausages can be rounder (like two spheres joined by a tube), but it's something that will improve in time, just keep it in mind. I think that, for the most part, the forms feel solid and like they're falling onto each other, (the long sausage behind does not fall onto anything though), but the shadows that you applied don't help at all.

Here's a corrected version (I'm working on Paint with mouse, so it's not perfect). The important things to remember is that the shadows will get bigger as the form starts to hang and separates from the form underneath; so it won't start thick right away. That suggests that the form is floating and it contradicts what you actually drew. The other aspect is that cast shadows have to follow the contour of the forms they're being cast on; the corrected shadow I made on the lower sausage does that, following the curved surface of the last sausage before reaching the floor.

Finally, be mindful of your contour lines, they're supposed to represent how the form turns and twists in 3D space; so their degree will change depending on how the form behaves. Both ends of the curves have to be the same degree, keep an eye on that.

Animal Drawings:

So, I've been looking at your insect drawings and they're pretty good as far as construction is concerned. You didn't make the animal drawings with as much care. The initial construction most of the time is good (although some intersection lines could help, on the point the bird's head makes contact with the body, for example), but everything on top feels extremely flat.

On your added masses, for example, you rarely did follow the contour of the forms they're sitting on, the best ones here are the ones where you followed the demos. Look at this. Notice that the added forms work like bags of fluor, or sticky gum, they warp and adjust to the construction they're being placed upon.

Your added masses a lot of the time look like blobs that do not adjust to the initial construction, or have random corners. In this demo you can see how that works. Corners usually suggest other forms existing right besides them (like on the shell of a lobster, for example), so try to avoid them unless they're necessary.

Your legs do not look like sausages at all a lot of the time, remember that making intersections on the places where they intersect each other helps a lot to solidify them as 3D forms. Most of the time you didn't construct the feet, instead trying to replicate them by observation. The best in this aspect are the bird's feet, which are actually constructed. You don't have to go overboard with that, but try to build their initial construction, add the planes, then add the toes or divide them where necessary. The intersection of the foot construction with the leg will also help you to solidify the whole thing.

Your heads are better in that they show a clearer path of construction, but still there are problems with how you follow (or don't) the contour of the initial construction. Finally, the main problem I see is that you tend to skip steps or whole sections, instead trying to replicate the animal just by observation. Remember, we're not trying to make pretty pictures here, we're trying to learn about constructional drawing. So, an awkward looking but well constructed animal drawing is better for our purposes than a beautiful, identical animal drawing with zero construction.

So, I'll ask you for 4 more animal drawings:

• One hooved quadruped

• One not-hooved quadruped

• One bird

• One animal of your choice

Add the reference photos to the submission as well.

Keep your line confident and clean, draw from your shoulder, take your time, don't rush it. Keep an eye on the demos, especially the informal ones, so you don't lose track of what you're doing. Follow the steps, from your initial construction, add forms, divide them into planes where necessary, add tertiary forms. Don't forget to add intersections where necessary, and to always take into consideration the forms you're working on when adding extra forms.

That's it, if you have any questions, I'll be around to answer them. Good luck!
