Your arrows have a very inconsistent width, which makes it a bit hard to understand which side is closer to the viewer. They should consistently get smaller as further it goes (but not have a wobbly variation).

Your sausages are nice. You got more degree variation on your curves than on the ellipses, so I think you got the idea but couldn't really apply it with ellipses.

The texture studies show that you understood them, but i think you had a bit of problem drawing on the lighter side of the texture. You can try and work a bit more implicitly, drawing only the shadows, not caring too much about the shape itself. That's more noticeable in your feathers, which look good, but are very explicit.

You dissections are very good. I like how you took every possibility to break the silhouette of the form.

The forms on the form intersection exercise are well done. I'd advise you to try drawing the back part of the intersection (the side we shouldn't see), so that the intersection is really visible through the forms.

The organic intersection is nice, the shadows and contour lines really give it a 3 dimensional form.

Arrows are great

You got a lot of detail on your branches, and that may be hiding information about the construction, but it looks nice.

Same for leaves.

Your plant drawings are really great. Only thing I can point out is for you to try to work additively, mainly with leaf shapes. But you did a great job.

Your arrows are awesome, I love the even spacing of the hatched shadows. You just need to be aware of which side is front or back, cause some of your arrows are getting smaller towards the front. (An example is the bottom left arrow)

The leaves are nice and fluid

Branches are too uniform and straight. The idea is to get a little more variation both in depth and wiggle. Your ellipses' degrees should vary more. You also didn't try the "knots" and ramifications, which is a nice exercise.

For the plants, most of your submission is the demos. They are very well done, but I wish I could see how you're tackling your own choices of plants.

I really like your mushroom and flower, but wanted to see some more variation in plant styles, like something with branch ramification, or some fruits or even a different cactus.

Your arrows are okay. Some lines are a bit wobbly, but most of them aren't. Be always aware of the perspective, and how the further point should be smaller.

The Ellipse countours are almost great. You could work on your actual ellipse drawing and also get more variation on the degree of the ellipses. To get it a bit more smooth you can add that to your warmups.

You contour line sausages look a bit square. I think that's because you're not really confident with your ellipses yet.

Also the degree variation is lacking.

Texture studies are really nice.

The dissections could be a little bit more implicit, working more with the light/shadow variations. But you achieved what the exercise asked for.

On the Form Intersections I think you didn't really get the idea. It's extermely hard, so I understand you.

On the bright side, your forms do look like they belong to the same area! There's no huge variation in perspective and that's the main goal of the exercise.

But on the other side, you didn't really get the intersections. You highlighted where the edges meet, but not the actual shape that is the intersection.

It is hard to understand, as stated in the exercise itself. But you can try to read it again just to see if it really "clicks" with you.

The organic intersection is very well done

Your arrows need more work! Try to add more curves to them, and be aware of the perspective (The Further point should be smaller)

What you missed on the arrows impacted your leaves. But your strokes are more confident there, so it makes it more convincing.

Your branches are great, but you need to be aware of the perspective and how it influences the degree of the ellipses. Every ellipse on your page has the same degree, but there should be variation.

I feel like some of your plants are lacking constructions lines. You represented the plants, for sure. But the exercise is about learning to build them, and I can't see some of the "building blocks", like the main leaf curve, or ellipse contour lines for spherical fruits (what would make them more 3D)

That said... Your demos are nice! You need to apply what you did in the demos for your own plants and you would achieve a much better "3D effect"

That makes more sense! I just couldn't wrap my head around a shape like your second example. And since there were no examples of sausages like the first one in the exercise page, I thought there really was something wrong with how I was thinking.

Thanks a lot!

Thank you! I tried to do bigger boxes, to try and get more steady with longer lines. But I now notice I should try some smaller ones, further from the border, to check the convergences better.

Thank you for the advices! I'll add it to my warmups.

First thing is that you didn't do the extending of the back lines. As is stated on the challenge page, the back "Y" is the hardest one to get right, and, by not tracing that after you did the boxes, you probably didn't notice how well you're drawing it. Pay attention to your back lines.

Furthermore, the hatching on the front face of the cubes is not really what it should be. You need to make the hatched lines go from an edge all the way to the other. You should also ghost those lines to get them very straight and evenly spaced. This will make your boxes feel more solid.

Also you got a lot of empty space on you page. It's a good thing to extend the lines all the way till off the page or when it gets too messy with other boxes. It can be a great visual queue to check if everything is really lined up.

Your superimposed lines are good. Ghosted lines and planes are also well executed

Ellipses are a bit more wobbly than straight lines, but they're meeting the standards of shape.

On the Rough perspective your lines get way wobblier than they have been throughout the previous exercises. Remember that, even when drawing boxes, it's important to keep your lines smooth.

Rotated boxes are pretty great, as well as the last boxes.

Overall great work.

Overall your lines are the main problem. The hard thing about doing this digitally is that I can't be sure if your program/tablet is acting weird or if you are not drawing it correctly.

On the lines exercises they are extremely wobbly, and should be done more confidently.

The ghosted lines/planes have the same wobble problem, even though they are close to meeting the desired path. You should work first on your fluidity and smoothness and later on accuracy. If you're accurate, but your lines are wobbly, it wont look good.

Same with ellipses, you're being accurate on keeping them consistent and packed together, but the lines are very wobbly.

The plotted perspective is great. The rough perspective is ok perspective-wise, but very wobbly lines.

Your rotated boxes are impressive, you really got close to nailing the overall shape, but again, your lines are very wobbly, so it doesn't look as appealing.

And for the organic perspective, it feels a bit rushed... By looking at your rotated boxes, I'd imagine this exercise would have great perspective applied, but it got a bit weird in some cubes there.

Main point here is about the lines. Work on them. Also... take your time to do the exercises. No need to rush.
