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

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!

Nice work on the monkey. Can I suggest some changes on the fish?

Nice assignment. When I took the photo of my drawing I thought maybe I printed the reference too small.

Hi Laura. Remember that the direction of the direct light does not matter for ambient occlusion. Its all about surfaces getting closer to one another. So In (A) and (B) I've added some shading to show this for the nose and one of the eyes. Using the same logic, as the cheekbone gets closer to the arch of the upper teeth (C) I would also expect to see some ambient occlusion. In (D) I've added some shading to show how the cavity of the mouth gets darker the deeper we go. I would suggest having a look at the solution in the 'downloads' section and compare it to yours, section by section. Make sure that in each case you understand why the ambient occlusion shadow is getting darker.
