Hello Mei, i’d be handling the critique for your lesson 4

Organic Forms With Contour Curves

Most of your organic forms are swelling and don’t keep a consistent width, very often you draw shapes that continually widens like ellipses, your organic shapes should only consist of two equally sized spheres connected by a tube of consistent width as viewed here https://drawabox.com/lesson/2/5/simplesausage

The degrees of your contour curves is all the same, because of that your forms seems to look very flat, you should give your ellipses a bit of a shift in their degree as you run through the length of the form https://drawabox.com/lesson/2/5/degree

Your lines are hesitant and wobbly, keep in mind to use your shoulder with a locked wrist to draw your lines, having confident and smooth lines will improve the solidity and believability of your forms https://drawabox.com/lesson/1/3/smooth

Insect Construction

it’s a shame that you didn’t provided the references you used here it would have been really helpful but anyway

You’re drawing really small, Drawing small makes things harder for us. it limits our ability to think through spatial problems. I would recommend you to take a full page for each insect that you’re drawing.

Most of the time you draw your legs with stretched spheres, you should build your legs using sausage forms https://drawabox.com/lesson/4/2/sausages

In your leaf beetle, cicada and your last one you drew legs that we’re not supposed to see through the body of the insects, i don’t have the references so i can’t tell if you’re entirely making the legs up or not but if we don’t see the legs on the reference then there’s no need to draw it, doing so will only add noise to our drawing
