Hello!

Congratulations on getting through your first lesson!

Now to the critique:

Lines: Overall your lines look nice, smooth and confident. However I see some curving on your lines so remember to take time to draw each line thoroughly using the ghosting method and use your shoulder always when executing the lines. Also, in the superimposed lines I see a little bit of fraying on both ends so remember to start your lines from the same point.

Ellipses: The accuracy in your ellipses is still off, which is completely normal, in the ellipses in planes exercise the ellipses should touch all the sides of the planes, in the tables of ellipses there should be no overlap between the ellipses and in the funnels the minor axis should cut the ellipses into two symmetrical halves. I am pointing out these for later reference. Your priority should be drawing smooth and confident ellipses. The thing I would focus on most is getting your ellipses to be evenly shaped. Accuracy develops overtime with practice.

Boxes: Your plotted perspective exercise is done really well! The only minor thing I would point out is that your crosshatching has been applied to different facing planes on different boxes, which makes it visually little confusing. This however doesn't the perspective on the boxes which you have done correctly. In the rough perspective remember to keep the width lines parallel to the horizon line and height lines perpendicular to the the horizon line. In the rotated boxes, the boxes further from center aren't rotating enough. Organic perspective exercise is done well.

Overall your exercises have been done well. The boxes section is hard for a reason and I wouldn't worry about those exercises. You can address the things I have mentioned in your warm ups but you are free to move on to the 250 box challenge. Good job!
