Hello Pomroka! Overall you've done a pretty good job, but there are some important things I want to comment on, let's go through everything section by section:

Starting with your lines they start off a bit wobbly on the superimposed lines, but by the end of the lines section you're doing a great job committing to your lines and drawing them confidently even if they're going to miss then ending dot, which is just what we're looking for!

So try to approach the super imposed lines the same way as you did on the other exercises.

Other than that you're doing a great job planning and executing them so nothing else to say! Keep practicing like that and accuracy will keep improving with time.

Moving onto your ellipses they're confident just like your lines on the lines section, which is exactly what you're meant to do!

Your accuracy is pretty good in general as well, there are a few cases in which you don't get the ellipses to touch the sides of the adjacent ellipses or them to touch the top or bottom lines, but in general I think you're aiming for them. Keep practicing and accuracy will improve with time!

Another thing is that your ellipses get a bit deformed at times. This applies as well to the ellipses on ghosted planes, which I think they're a bit more deformed than the others. You might be thinking that the centre of the ellipses is the same as the centre of the planes or that you should modify the elliptical ellipse shape so it touches the contact points, but this is not the case. Ellipses have to be symmetrical and have the same shape regardless of where they are, so the only things you can change is how wide the ellipse is, which position it is in and their size.

Lastly on your funnels sometimes you aren't aligning the ellipses to the minor axis. Make sure you always aim for the ellipses to be cut symmetrically by the middle line even if that means you need to ignore the initial curves. Pay also attention to the angle of the ellipses as well. They have to be cut symmetrically by the line, so they can't be tilted.

Finally in your boxes a few things:

-Sometimes you're repeating lines that were off but no matter how off a line is, don't repeat it. Keep going as if it was correct as drawing them will make the drawing messier and can encourage bad habits like automatically redrawing your lines after you miss.

-On plotted perspective you did a good job following the instructions of the exercise, nothing to say here!

-On rough perspective you are already doing some good attempts at guessing the perspective, but you still seem to have trouble at times keeping height lines perpendicular to the horizon line, and width lines parallel to it. I know it's hard, but make sure you always are aiming for it. You can check if the starting and ending dots are correct or not, and if you find that they aren't you can change them. You can put down as many dots as you want as long as it's before drawing the actual line, so give it a shot!

-On rotated boxes you started well apart from the repeating lines issue I mentioned, but you haven't finished it! So I'll ask you later to finish it completely.

-On organic perspective the main thing is that I think you aren't drawing starting and ending points for all of your lines. If this is the case make sure you do it because it's super important for applying the ghosting method properly.

Remember also that you can add lineweight to the parts of outer lines that overlap with other boxes to clarify which ones are on top and which behind, so give it a try next attempts you have at the exercise!

Overall you're doing a good job, but I want to make sure you can draw lines confidently without repeating them on boxes, so I want you to do one more page of rough perspective. Make sure you draw all lines only once! And I also want you to finish the rotated boxes as you didn't finish them.

Good luck and keep it up!
