Hey there emirmdd, glad to have you on board.

Starting with your super imposed lines, you are drawing them confidently with little in terms of wobbling so that is great. As you continue to practice this in your warm ups try to experiment with different rates to try and get your grouping tighter. With your ghosted lines you are using your shoulder well and accuracy will develop in time and with practice.

With your ellipses in planes you are drawing them confidently so that's great. Your drawing through is a little spread out so just keep practicing using your shoulder and getting control better. You are doing pretty well at hitting the points on the planes you need to so that they remain within the bounds snugly, but with your tables exercises there is more room for ambiguity as the ellipses aren't packed in tightly. With your funnels exercise you are doing pretty good at keeping your minor axes aligned to the funnel axes, you are getting a little wild in your control of them and your follow up passes are pretty off the initial ellipses so try to tighten that up.

Moving on to your rough perspective, your lines are looking pretty confident. Your horizontal lines are parallel to the horizon and your verticals perpendicular so you have nicely oriented boxes. Your converging lines, while off target, are where we expect them to be and your check lines are correctly applied. I do see some redrawing lines which you shouldn't be doing - instead you should be preparing every line, ghosting, and confidently executing.

Now let's take a look at your rotated boxes. Overall this is a good job. Our only goal here for students is a complete attempt to the best of your abilities and you've done that here! Your lines are a little shaky here from not using your shoulder confidently so remember no matter what to always ghost and use your shoulder for swift decisive movements. Some of your boxes are packed together nicely, while some could be closer so you can better leverage adjacent lines to serve as perspective guides. Additionally, you weren't rotating your boxes so much as skewing them as explained here so give this gif some more study now that you have context to see how the motion of the vanishing points drives the box rotation.

Finally, let's look at the organic perspective. Your compositions draw the eye in nicely due to the gerat use of large foreground elements and the scaling of the boxes shows a recession into the background. You are beginning to tell the great lie of the illusion of 3d space on the page so good job. You could have afforded to draw some more boxes for practice, but it's not the worst. Your perspective is for the most part still divergent - near planes smaller than large planes, but that's nothing the 250 challenge won't cure.
