And it looks like a good start.

I think you did a great job at capturing the overall shape of the pear and you also noticed that it didn't have the "curve/roundness" which was great! My suggestion is to make it even more diverse in terms of shading by adding more mid-tone into it (on your pearl I can only see 2-3 values, which isn't ideal enough to express the desired result). You can try to darken the border between the light and dark, but not as dark as the shadow on the pear. Hope this help

The style is really cool and I like the sketchiness! Solidify your shading more. Maybe use a wider pencil stroke. This will make your drawing even better.

The second one is perfect! Strong graphic design work there.

Thanks for sharing! A bunch of improvement already. Here’s a demo I made for other students that might be helpful here too. I like how you concentrated the darks on the second attempt. Making the eye the darkest element, while everything else is light around it, makes it way more interesting than what I did. Keep making interesting choices like that! Good stuff 👍

You did a good job designing your shapes here even though you struggled 👍 The only thing I would advise is to be careful about outlining the highlight shapes. You want to try to use the edge of the darker value to define the shape instead of a dark line. It's good practice in pencil dexterity. Otherwise, looks great!

I think you can incorporate the 2nd darkest value, and even the darkest value, into the pear itself rather than containing them to the cast shadow. If you use those values for the dark side of the pear, the remaining three light values can be used to add more information and dimension to the light side of the pear. Also, try starting your grey values even lighter, as it seems like the value scale skews dark pretty quickly, compressing the range you are working in, which can give the effect that there are less values than you actually have. Otherwise, I think you did a great job simplifying the shapes and keeping accurate proportions. Keep going!

I would recommend starting your 2nd lightest value even lighter, so there's more of a gradual progression in the value scale and it doesn't get too dark too quickly. Also, I like that you have the line separating the areas of shadow and light on the pear as this is an important division, though keep in mind that this is still a real plane on the pear so it will show up like a thicker value group shape rather than just a thin line. I think you definitely succeeded in adding dimension with the portrait, so really nice job, keep going! :)
