Hello Anbarbosa, congratulations on completing L4! and thanks for checking my homework :)

Here are my thoughts on your submission:

-Shadow shape seems wobbly on Mantis, though this is the only instance where that happened.

-Forms are very solid, and you add mass in a very convincing way.

-Worked subtractively on the Firefly's (Libélula) abdomen. The Drawabox approach is that you should always build forms additively. So next time try using a small organic form, then adding onto it, instead of having a large form and making a smaller one inside.

-I suggest using more line weight on the Spider's legs, since it can get a bit visually confusing with the shadow shape.

Conclusion:

Very solid submission, very good stuff. You show a clear understanding of the material and manage to construct very solid and convincing forms.

Full speed Lesson 5!

Best of Luck
