Hello!

Your lines are good for the most part, although there are some wobbly ones. Remember that right now you should prioritize confidence over accuracy, the later will come with time!

You did great on the perspective exercises! Although for the organic perspective one it would have been better if you drew the boxes closer to the viewer bigger, and the ones that are far away, smaller.

As for the ellipses, you drew through them too many times! Remember that the exercise said to draw through each ellipse only 2 or 3 times. You should ghost them as much as you need to, before drawing them.
