Hi alturass, welcome to the inky side. We have cookies...which you must fork over for your critiques...thank you.

Let's get started.

Your line work is definitely confident. You are showing a clear understanding of executing your lines with the shoulder and not being worried with trying to mindfully steer your lines, so this is great. Your ghosted lines are confident, but sparse. Empty space = missed opportunity for growth, remember that! The instructions call for a filled page of ghosted lines and I certainly wouldn't consider that filled, but I won't be asking any additional work because of it.

Your ellipses are likewise very confident, but get a little loose in some places in your drawing through like in some of the planes, but I can't complain. They are shaped nicely, no flat portions or points, and you are definitely using the ghosting method and your shoulder. Your ellipses in planes are hitting the mark usually but sometimes you are missing the edge of the plane so your ellipse ends up floating arbitrarily in space. The concept of securing each mark in its bounds you previously set is a hallmark of constructional techniques and it starts with these basic concepts. With your ellipses in tables you're doing a lot better in getting those ellipses to be packed tightly and leave no room for ambiguity. Your ellipses in funnels are also great and for the most part the minor axes are all aligned to the funnel axes, good job.

Moving on to your rough perspective boxes you're doing great in keeping vertical lines perpendicular to the horizon and horizontals parallel resulting in properly oriented 1 point perspective boxes. Your lines are crisp, confident, and planned indicating a good use of the ghosting method, and your converging lines are on the right track. In time your lines aimed at far off points will get more accurate as long as you keep practicing. I do see a couple times where you re-draw your lines and you should not be doing that as "fixing" "mistakes" usually only leads the viewers eye places where it normally wouldn't have noticed so you're almost always better off living with your first result.

Now looking at your rotated boxes you did a nice job here. You drew it really large which is great for giving your brain room to think through this stuff, and it also helps keep your lines neat and clean. Your hatching is mindful and not rushed and you continue to be using your shoulder and ghosting really well. In terms of packing your boxes you could have gone tighter to better leverage adjacent lines as perspective guides, but this isn't the worst case of it. You are rotating your boxes some, but you could push the rotation way more. Watch this gif a few more times and watch how you can push the rotation more by moving the vanishing points further along the horizon line. Other than that you've done a great job here.

Finally, let's take a look at your organic perspective. First of all if you look here in the example homework there are three framed compositions. You were instructed to draw frames around your compositions here. Now you have mentioned you've done these lesson previously but please do not feel that that is a reason to cut any corners. Drawing is a mental game of discipline just as much as a physical act. Regarding the actual exercise, your second page is much more successful than the first: you have overlapping forms, large foreground elements, small background elements, all of which combine to sell the illusion of three dimensional space on the page. Your boxes are off to a good start, with a mind for convergence and overall pretty good job.
