Your textures look great and your contours around organic forms effectively reinforce the illusion of them being 3D.

I felt your illusions came apart a little during the intersection exercises. The junctions between curved surfaces can be wonky and I felt that some were under- or undefined.

I marked three of your intersection exercises (found here https://www.reddit.com/user/BowtieBuck/comments/qc77ch/feedback_for_minnori_lesson_2/). The comments for this marking are below:

Green Marks represent intersections that looked good.

Blue Marks represent intersections that are too shallow or whose positions are not effectively communicated with line weight.

Pink Marks represent intersections that I thought could use work:

Pink 1: This intersection between the sphere and the cylinder felt too shallow/straight to effectively describe their position in space which appears at the same depth by the looks of their size.

Pink 2: At this intersection between the cube and cylinder, you have edges of the cylinder peeking out, which suggests that the minor axis (and it's volume) should be visible on those sides of the cube. Alternatively you could raise the cylinder and cut off the edges completely. That said this is an exercise so I suggest trying it, even if you do not get the result you are hoping for.

Pink 3: At the intersection between the flat surface of the cone and the sphere you have drawn a concave intersection where it should be convex. Intersections should follow the contours of both forms and the contours of a sphere push outwards.

Pink 4: This was a case of not enough details for the viewer to understand the intersection in 3D space. This appears to be caused by the weighted edges not reconnecting to any of the outer lines.

Pink 5: I appreciate that you attempted this intersection between a sphere, cube, and cylinder. It is not easy to try and imagine complex intersections but you did well. I felt however that the intersection was a little messy and the connection between the sphere and cylinder does not make it clear which dominates at the far end of the cylinder.

Below the first row you will find the above intersections redrawn roughly how I imagined they should have been drawn. In general however I suggest doing this exercise for your warmups and push your shapes deeper into one another to practice combining those longer contour lines.

Other than that. Well done on completing lesson 2. If something I said was unclear or incorrect do not hesitate to tell me.
