Heya, thanks for your work !

First things first you're doing great! I don't see that much wobbling in your lines so you're drawing fast enough and got confident lines, there is some that are still a bit hesitant but you'll get them with practice. Your pages of superimposed lines are a bit too loaded don't forget to not grind to much. Also it was not mandatory but you did not do any arcs with the superimposed technique, you might want to do some for your next warm-up session. You should watch out for fraying lines on both ends, the line should not fray on the starting dot of the superimposed lines.

For the ellipses you should only draw through each one no more than 3 times (2 times preferably). otherwise they look good and confident, some don't reach all the sides in the ellipses tables but again practice will help with that.

Lastly the boxes, you shall NOT draw a mark MORE THAN ONCE, this is especially for your first page of organic perspective, if you wanted to add line weight you should only do it for the part of the line that overlap with another box and not over the full length of the line.

Overall you did a good job, the rotated boxes exercise is well done and you already show some confidence in your markings, now you need to practice accuracy which you'll do through your warm-ups by doing ghosted plane and superimposed lines.

Don't hesitate to use the ghosted planes you make to train ellipses as well.

I saw that you already finished the 250 boxes challenge, remember to not rush things and take the necessary time for each exercise / warm-up.
