Hello Shimone! Overall you've done a pretty good job, there are a few things I want to talk about so let's talk about them section by section!:

Starting with your lines you're overall doing a pretty good job committing to your lines even if they miss the neding dots which is great! Keep practicing like that and your accuracy will keep getting better and better. Other than that you're planning through all your lines, applying the ghosting method correctly, and there isn't visible fraying in your lines in both ends neither. Good job!

Moving onto your ellipses you're also doing well drawing them confidently! The main thing is that the accuracy is still a bit off at times, so try to keep reminding yourself before drawing each ellipse that the goal is to touch top and bottom edges of the tables of the ellipses and to touch and not overlap the ellipses at its sides.

The ellipses on the ellipses on planes are pretty good as well, though at times I feel like you're trying to modify the ellipses so they fit the planes. The ellipses need to have a symmetrical shape no matter what, so make sure you don't try to change certain parts of the ellipses breaking the symmetrical shape to make them fit.

Lastly on your funnels you're doing a pretty good job alligning them to the minor axis overall! They do get a little bit missaligned at times though, make sure you always have alligning the ellipse to the minor axis your first priority. If you need to ignore the curves to do it because they're off it doesn't matter, ignore them and allign them as best as you can.

Finally in your boxes a few things:

-Overall you're not getting confused and you maintain the confidence you have on the previous exercises in the boxes section, great job!

-On rough perspective you're making some good attempts at the perspective guesses already, and you've done well drawing the boxes cleanly, only thing is that you 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've done great rotating most of the boxes and keeping them all together! Only thing on this one is that you've sometimes repeated some lines that were off. Make sure you always leave them be no matter how off they are, as drawing over them will make the drawing messier and can encourage bad habits.

-And lastly on organic perspective you're drawing the boxes very clean and making some good attempts at the boxes already! The perspective has issues but that's not a problem as you'll work on it on the box challenge. One last thing is that you can add lineweight to the outer parts of boxes that overlap other boxes to clarify which one is on top. Give it a try in future attempts!

Overall like I said you've done a very good job, so I'll mark this as complete. Make sure you do warmups from now on and good luck on the box challenge! Remember as well to ask any questions you may have and keep up the good work!
