Hello Brilte! I am also a beginner, so take my feedback with a grain of salt, BUT I hope my feedback can still be of use! Although I don´t think there is much I need to correct..

  1. Lines

Your lines are very well drawn and get less and less wobbly as you practise. It looks really good and the ghosted planes exercise is also done nicely!

  1. Ellipses

While I think that it would have been good to have straight lines for the panel of ellipses (in order to see clearly, whether the elipses touches or misses the line), all your ellipses look pretty confident and clean. You also didn´t miss to circle them several times, so that was successfull as well.

  1. Boxes

Especially the rotated boxes excercise is stunning! I struggled a lot with it and you managed to portray the sense of perspective and depth very clearly! My only critique in the boxes excercise is that you drew over your lines several times, which is not sth we want to do. The line should be done once and even if it is a bit wobbly, be kept the same. Other than that, all tasks of this section look great!
