Hey what's up. It is critique time :)

-Let's start with your arrows.

I notice that one page for the majority does not compress but the one on the left does do it. The other page of arrows show more of compression like shown in this example. Don't forget to give a bit of line weight when an overlap is going on.

-organic forms

On your first page where ellipses are done with only one fully done ellipse. For a confident ellipse you keep ghosting around the minor axis until you put down your mark and draw through 2-3 times to make it close properly.

Some sausages look funny where it is very round on one side and more deflated as it goes on.

Most of them seem to be done incorrectly on the first page with off axis allignment. For the axis going through ghosting works to keep it on the middle as close as possible making ellipses more accurate too as long as you don't turn them too much. You did however, use ellipses to make it look like it's going through 3D space more.

The second page you did went great compared to the first page sausage form wise! Only things about those is that make sure the line is going completely going through the sausage and that even if they are only contour lines, they should still be drawn like an ellipse when ghost and only draw the outer side and make sure to overshoot it so it looks like it's going around the sausage. i'd suggest reading through the page of organic forms again and add them to your warm-up list. I had to mention it earlier but every exercise except textures can be added to your warm-up list.

-texture analysis

I's will be difficult to give critique on a page that is not completly filled but i'll do my best to give critique on what you have. This will be added to revisions as this page is not shown complete.

Looking at the first analysis you did only look at shadow shapes. Your gradient on the other hand is lacking some shadow shapes. It is easy to see the black bar the beginning and the white bar at the end. Don't be afraid to really push the dark side that slowly fades. The beginning is very dark with a lot of shadow, the middle is the transition, the in between and from the middle more light seeps into the gradient where shadow shapes appear less and less until you reach the far right where barely any shadow shapes are visible. Also fill the shadow shapes in properly. too much white can distract you. a way to look where cast shadows are is by squinting your eyes. by squinting details fade away more and shadow shapes come more and easier to see.

Alligator skin in the middle part look to have complete shapes that don't have much to do with shadow. Could you show your ref of that one? i'd like to be sure what you did there. Can't say much anymore here as the other gradients and texture are missing.

-dissections

I don't really see any of them wrap around the form like this one

when going around the form the edges have way thinner forms compared to the middle. For example; think about how a marble rolls around a ball. When you start seeing it you only see the top and as it rolls towards you (for the sausage towards the middle) the more you see of the marble. When it has reached the middle it will roll away and go around the form slowly being less visible again. About breaking the silhouette, you did it here and there but not consistent enough. Best i can think of is like the marble again but you can only see the tippy top of it breaking the form. I did see that one of the insides of the dissections is a raspberry? It looks very flat compared to the bubbly looking fruit. I think with things like that you can have the outter side have some bulbs breaking out of the ellipse to make it appear bubbly.

-form intersection

Let's start with that yes, you did do 4 pages as required, one page needed to be boxes only.

When doing cylinders give them an axis. Don't keep shapes alone, they have to be with the other form intersecting or not. You did keep perspective consistent and shallow but do give your cylinders variety as i noticed they are a bit same looking with angles.

-And finally organic intersections

You said you had trouble with these because you removed the spine/axis. Thing is, you don't have to remove it. you start with the sausages and then can add the spine and then add the contour curves.

They also don't seem to look simple. Keep it simple like its 2 balls being connected with a tube. You did give them a shadow that follows the form they're on but keep in mind to also ghost those. If the sausage stays close to the one its laying on it remains a small shadown and when it stays relatively high and doesn't when it doesn't follow it to the end.

Last thing to say is that some of your sausages float. They shouldn't and have to be like water balloons that are dropped onto each other. they don't float but they sag following the form of the one it's laying on. Maybe unfomcfys video will clear some things up

All in all, you had a lot of trouble and i'd like to see some revisions of a couple things either not done or not understood.

If you have any questions feel free to ask and i will try to answer them to the best of my ability.
