Hello Leefebul! In general try to keep your comments to specific questions instead of critiquing your own work directly. For example you could ask "I struggle trying to draw contour on the appropiate degrees on these perspectives, or I'm struggling drawing organic forms on these situations" These kind of specific questions make it way easier to help you in whatever you're struggling, so try to do it next times whenever you want to ask something!

Starting with the organic forms with curves I think the main thing you're struggling with isn't varying the degree, which I think you're doing a good job on, but the allignment of the ellipses with the minor axises. Remember that the minor axis must cut the ellipse in 2 identical halves, and in your sausages sometimes your ellipses are tilting too much, which makes this impossible. Make sure you keep an eye on that, and maybe try to actually draw the major axis on some of the ellipses so you know what I'm talking about.

About your insect drawings, overall you're doing a great job and they show a very good grasp of form. They feel very solid! You're also doing a good job defining the intersections between most forms and using the sausage method, though there are a few cases on which you don't draw some intersections or make some mistakes on the sausages you draw.

About the intersections, in general every single form you draw should be connected to whatever you had drawn previously on your drawing by defining the intersection between forms. Here are some examples where you didn't add intersections to some forms.

Another important thing is how you approach simple organic forms. On the first part of the lesson you did a good job with all of them, but on the insect drawings you make sometimes stretched ellipses instead of sausage forms. Always remember that the simple organic forms we use here are formed by 2 balls and a tube of consistent width. The tube cannot grow in the middle! Here are some examples.

Pay attention to the part on which I add masses to a simple form. Whenever you wanna draw a complex form always approach it like that. First drawing a simple form, and then add more simple forms with intersections making clear where the forms connect until you get the complexity you wanted.

On textures you haven't done much on them, but in general you've done a good attempt, like on the fur of the spider you drew. Main thing is that sometimes you do color some form shading on some forms. Remember that you should never do generic form shading on drawabox exercises like you did on the eyes of the bugs. I know it's tempting to color them but do your best to restrain yourself!

Another thing is that I recommend you always take a photo before adding texture and cast shadows to your drawings. It will make much easier to critique and the critiquer will be able to pick up more things that can be useful for you, so don't forget to do it!

In general like I said you've done a pretty good job, so I don't have much else to say. Make sure you focus on drawing intersections between all your forms, making clear how everything connects, don't forget to ask any questions you might have, and move on the the lesson 5!
