Hello, congratulation on finishing lesson 2. I'll be only pointing out the thing that needs to be improved and Here are my observations:

  1. Organic Arrow

On the first page, you seem to have difficulties controlling the perspective of the arrow but on the second page you start getting better over the perspective, I think next time try more extreme changes on space between the curve since on the first page difference in size between the curve is so subtle that is kinda hard to differentiate which closer and farther away and of course be mindful of the size of the ribbon. Please try to add some line weight around the overlapping part so it'll be more understandable which is back and which is front.

  1. Organic Forms with Contour Lines

For the organic form with a contour curve, I feel like the curve is a little bit stiff and doesn't show much dimension, so my advice is that when you ghost the curve, try to ghost the whole ellipse, but when you put the mark, only draw the part that wraps around the form, so you will get a better sense of how the ellipse turns in space and it will be easier to get that hook.

  1. Texture Analysis

Try adding more cast shadows around the area that is closer to the black bar because I feel too much white space around that area.

  1. Dissections

Try to make the texture is wrap around the form.

  1. Organic Intersections

draw the cast shadow to follow the form of the object they're being cast on.
