Hello again GrumpyOwl, I hope things are going well with you, your art and in life.

I will go through your exercises now and see if I can give constructive feedback.

Organic Arrows

Your arrows are nicely presented with good control of space on the page. Good job on reinforcing the overlaps with superimposed lines. Keep drawing all lines from the shoulder and maximize your mileage using that shoulder pivot.

Watch the shape of your arrow heads, they should be symmetrical, equal width both sides. Also, while I can see you have done this for the most part, just watch out where you increase the amount of space between each successive curve as it comes forward in space, it really does help sell the illusion of depth.

Organic Forms

Again, your control of space is excellent with most ellipses touching the sides of the forms, well done. Do watch the shape of your forms though, try to think of these as 2 equally size spheres connected by a tube of equal thickness. what helps for me, is drawing two spheres and connecting them with curves as a warm up, just to get a sense of the form. Your second page forms are a lot more consistent, well done.

Texture Analysis

Great work on these I think the best I've seen so far. You have a great sense of gradation from dark to light, I learned a tonne from these, thank you!

Texture Dissections

These are nicely rendered and you've wrapped them around the forms really well. Hopefully someone a bit more experienced with texture can give you more constructive feedback on these, as for me I will be studying these for sure ????

Form Intersections

You mentioned this one was a bit of a struggle, I think most of us are struggling with this one too. I had a bit of a breakthrough recently when I concentrated purely on 1 form intersecting with a single plane, it's starting to make a bit more sense to me. So my advice would be start simple like that, for instance, what would it look like if a cylinder intersected with a flat plane? Overall though I think you managed to get quite a few of these and your forms look great, with foreshortening fairly consistent for the most part.

Organic Intersections

You're starting to get the hang of those organic forms.. Contours are nicely wrapped around and there's a good sense of weight to the pile, maybe the foreshortening is a bit extreme on the top forms, but that's really a nitpick. Do try to watch your shadow shapes though, I find these can get tricky too. I guess it would be helpful to buy a bunch of water balloons to study the shadow shapes, I think I might try that myself in future.

Great work overall GrumpyOwl, no hesitation in recommending you move to Lesson 03: Applying Construction to Plants.

Good luck on your forward journey!
