Hey there, I'm still going through this lesson myself so I'll keep this pretty short and stick to what I've got a grasp on.

Your organic forms are alright, but I think they could use some more work. For the purpose of this exercise, I would recommend sticking to contour curves rather than the ellipses, since curves are what we use to help establish the 3D forms in our insects. A few of your forms are also tapering on end, with one end noticeably smaller and more compressed than the other. Generally you should try to keep both ends of the form about identical to each other. If you think of them as two similar shaped spheres at each end with a tube connecting them, that might help with getting them more into proportion.

As for the insects, they look pretty good! You've got the head, thorax and abdomen clearly defined and the sausage forms for the legs look pretty good and well connected. I will say that some of your insects (such as the moth) look a little flat, and I think that's a result of using top down poses. That's not to say you shouldn't utilize those views, but for getting a better sense of 3D space, I think picking more dynamic poses might help you out in that regard. Look at and try some of the demos like the wasp and black widows ones to see examples of more '3D' poses and how to do them. Finally, in regards to texture, in the future avoid attaching short little lines around the outline of the insects. It doesn't really convincingly convey any sense of real texture and can actually distract from the main forms we're trying to look at. Rewatching the main video can help you out here, as Uncomfortable goes into how to apply texture near the end.

Overall I think you're doing a good job and your insects are put together nicely, you just need to hone in a little bit more on your forms and your texture and you should be good to move on to the next lesson. Good luck and have fun!
