Hey there altharmir, welcome to patreon and official critqiues! Let's get started.

With your super imposed lines the big thing I'm seeing is a lot of wobbling going on. At this stage you should be focused on using your shoulder to exectue confident swift marks and worrying about accuracy later. Keep working on learning to engage the shoulder to drive the motion of your arm so your lines can have better "flow" and as you do this accuracy will naturally increase. Much of the same goes for your ghosted lines. This isn't a huge deal though, it just means keep practicing these exercises in your warm ups (but don't grind them!) and things will get better one step at a time.

Your ellipses are showing some glimpses of much more confidence than your lines. While there are some regions with wobbles or flat parts, overall you are doing a good job of drawing through your ellipses and keeping the groupings on these passes tight. In your tables of ellipses you are doing a pretty good job of keeping everything packed together to avoid ambiguity in your ellipses, but where you could improve on is keeping your ellipses consistent in alignment and size within each row of the table. With your ellipses in planes you are making contact with the edges of the planes correctly and thus firmly cementing your ellipses in space. Make sure you're always using the ghosting method and trying to use that shoulder so that you can improve the flow of these. With your funnels you are successfully aligning your minor axes to the funnel axes but things are a bit more hesitant here due to trying to balance so many constraints. Focus on ghosting and trust that things will fall into place when you confidently execute.

With your rough perspective we are seeing a common problem that students have when they get here. As they move from abstract exercises to drawing something a bit more "real" they can become overwhelmed. Your lines are showing a lack of ghosting and confidence so remember every line should be prepared and ghosted. Your alignment of the boxes isn't too bad - horizontals parallel to the horizon and verticals perpendicular so good job there. Your converging lines are what we expect for a student here and as you continue to gain mileage like in the 250 box challenge your accuracy for drawing lines to distant targets will definitely improve.

You did a good job pushing through to completion on the rotated boxes. The only goal here is for students to try their best so they can be exposed to new types of spatial problems and ways to solve them, and quite frankly a correct execution is not expected at all. So you have accomplished the one and only goal here, good job! In terms of the exercise itself there are some things I can point to for improvement. In some of your boxes your adjacent lines aren't staying together or parallel so you can't properly leverage them as perspective guides so read that section again to try and understand it. Your boxes are often not rotating so watch this gif and try to internalize how the rotation is driven by moving the vanishing points along the horizon line. Overall though, for a first attempt you did fine and should be proud for persevering through it!

Finally let's look at your organic perspective. Your lines are starting to get a bit better here. Although I want to point out your redrawing of lines which is something that should not be done. All lines should be prepared, ghosted, and executed when you're ready to live with the results. Drawing over lines only makes mistakes more obvious and adds visual noise. Your compositions are nice; there is a lot of movement and good overlapping of the forms which makes the viewer's brain believe these forms all exist in a single shared space. Additionally you're doing a pretty good job of scaling your forms to have a clear fore, mid, and background. These two principles are key to creating the illusion of three dimensional space on your page which is our main goal with drawing. To push the illusion more you could have added some very large forms in the foreground but this is a nice start.
