complex AO Study, A little bit hard to differentiate between ambient occlusion and form shadows. Any feedbacks will be greatly appreciated

Nice job on the fish, and you got down correctly all the key areas of occlusion for the monkey. When it comes to separating occlusion and form shadows, most of the darkness you see when an object is under direct light will be the form shadow, but there is a gradation as the occlusion fades out or a strengthening as it interacts with other planes, including the floor. Think of a soft, diffused light source coming from above. So in this monkey example, you will see some soft general shadows, underneath the face/cheek area and a soft shadow underneath the brow bone, similar to the gradation on the sides of the fish. Generally, the shadows will become darker the closer they are to the floor (or another plane, as in the case of tight crevices) and lighter the further away and more open they are.

I improved on the drawing because my lines were too heavy in the previous submission. I tried to focus more on the ambient occlusion itself

No idea if it’s entirely correct and the soles of feet I assumed would be in contact with the ground.

I don't have a printer so I had to draw the monkey

Here is my take on this exercise. I am not quite sure about the area around the fin or about how far the occlusion shadow should spread but I will get the hang of it with some time :)

It took me a while to get to this exercise so I did a couple of extra views. I thought the airplane would be fun to do, but the top view became more of a rendering exercise because of its flat silhouette. Anyway - it was tempting to add half tone to the plane sketches to bring out some form, but I pulled back (even erased) in hopes of concentrating on AO.

In ambient occlusion the question to ask your self is what fraction of the light in the hemisphere above a surface's normal can see light (and remembering that the flux of incoming light drops off with the cosine of the angle---so light from grazing directions is not as important). With AO we often imagine the entire sky is lit with ambient light, but that's a simplification. I think your fish may be a bit too shadowed. All in all, great progress!

After checking the solution for the monkey, I went back and had another go and tried to pinpoint where I felt like I was consistently making mistakes (not going dark enough, giving the AO too much of a direction, etc)

Continuing to attempt ambient occlusion- first by attempting the demo video and doing two of my own in graphite. Feedback always appreciated.

Good job! This ambient occlusion work makes well feel the volumes.

This is very hard, but I’m okay with the results. I'd hugely appreciate constructive feedback for the homework. Thanks :)

Good work!! You are definitely getting the hang of this. Here are a few suggestions on the mug. The other two look solid!
