Dorien Iten has some free lessons on this here on Proko and they are excellent. Might add some missing bits for you. But I hear you. breaking things down into distinct value groups in this very specific way was and still is a tad confusing. You've got the highlight version above, but Stan also talked about matte surfaces, that generally don't have a highlight due to the surface scattering the light that hits it. If you recall, a highlight is the reflection of the light source. The matte version might also help simplify the problem.

This is a good start. I would like to add a little advice. The reflective/bounce light should not be lighter than anything in the light. It is still part of the shadow. The one reference photo for the egg standing up seems to have multiple light sources which is not idea especially if you’re a beginner.

Wow i thought that both were done with pencil. Good control!

You did pretty good handling your edges, but the shadow values are not nearly as dark as in the reference. This egg has complex lighting on it. If this is one of your first attempts at shading I recommend something more clear and direct with a single source. Try this egg:

Those are good! Next up you should try putting those irises on an eyeball and make that 3d. That's very appropriate since we just learned about spheres. After you get the hang of that, the challenge will be putting those eyeballs into eye sockets, and wrapping eyelids around them in a way that you can still feel the round eyeball pushing through!

I watched this movie many times

I know! Sorry it's been slow. My paternity leave is almost done and lesson schedule will get back to normal!
