This is definitely moving in the right direction, but I can see a number of places where you're still building upon your construction by adding 2D shapes, rather than sticking to complete, enclosed, 3D forms as I explained previously when talking about avoiding altering the silhouette. Here I've pointed out where you've used a number of 2D shapes.

In terms of doing this in a way that retains the illusion that what you're constructing is 3D, take a look at the ant head demo I provided previously, and compare it to the way in which you approached your ant's head. In general, you definitely should review the other demos I provided as well.

All in all, these are things you can continue to address into the next lesson. Since you're moving in the right direction here, I'll go ahead and mark this lesson as complete.
