Hello allipses!

Starting with the organic forms you're doing a pretty good job drawing confident lines and drawing the forms consistently, the only issue I can see is that sometimes you draw some of the ends of the sausages a bit bigger than the other ends, the width of the sausage needs to be consistent, so keep an eye on that.

Now into the insects, you're overall doing a great job on making them look solid and believable! The main thingy I've found you're having trouble with is the leg forms, which you are already making a pretty good job on them, but sometimes they are a bit different, like on this one on the grasshopper, so keep an eye on that on lesson 5.

Second thing is that you aren't drawing the intersections between forms which is pretty important, so don't forget you do it on future drawings. Here are some examples on the beetle

Last thing I wanted to comment on is that sometimes there are some additional forms you aren't drawing, which is fine since the important part are the basic forms, but it's good to practice them as well. Some examples too on the beetle

Other than that you're doing a pretty good job, don't forget to ask any questions you may have, keep up the good work and good luck on lesson 5!
