Yup, I believe you've shown considerable improvement in the areas I pointed out. As such, I'll go ahead and mark this lesson as complete.
One small point about this insect. On the big spines, you added a great many contour lines along its surface, and most of them don't actually end up contributing. The most meaningful contour line in this regard is going to be the one that defines how the spine connects to the larger form, and when done well enough, no additional contour lines are needed. So always draw that one first, then try and ask yourself whether you really need to add additional contours to better convey how those surfaces sit in space.
It's entirely normal for students to just assume "no it's not good enough" and pile on more contour lines, so you need to really be honest with yourself. Piling on more contour lines than are necessary just adds to the clutter, so you need to determine exactly how many are needed, and not overdo it.
Next Steps:
Feel free to move onto lesson 5.
