Hey Fex, i'll be reviewing your homework today.

First of all, congrats on finishing all the exercises!

Lines

Overall your lines are pretty good, they are confident with no wobbling, there's no fraying where the lines begins, the lines are not arching, there's no freehand lines you plotted all the dots correctly, so great job! I would recommend you to draw more lines, it's okay if they overlap, like in the uncomfortable's example

Ellipses

In these exercises you drawn through the ellipses 2 times mostly, they are within the boundaries of the forms, not overlapping and are confident, that's great!

Boxes

The same stuff from the lines applies here, but i'm gonna just reinforce that you never must repeat a line, you should just consider as if it were correct and move on, also be careful when applying line weight, you should do the same process of ghosting as if it were a new line, so it will be exactly on top of the original one.

Other than that, you drawn trough the boxes, on the rough perspective exercise all the horizontal lines are parallel to the horizon line and the line correction was applied, as it should be and everything else looks pretty great.

On the organic perspective some boxes are kind of foreshortened but this will get better once you start the 250 boxes challenge.

Once again congrats on finishing those, i think you did a very good job and i hope this was helpful!

Good luck with the 250 boxes challenge!
