I tended to focus on 3d shapes only in this exercise although I did add what was considered too much detail or black fill in a couple.
My view is to focus on consistent pen weight for as long as possible. Only use extra where it helps with a potentially confusing situation that it will help clarify. Such as ensuring one of two crossing legs is in front of the other.
Spines, antennae etc are all 3d shapes in space so they are construction not detail. You could have one long, thin tube for an antenna and then add segmentation around. That is fine.
If you see clear cast shadows then you can use them but I think clear construction is more important.
