Hey there,

On the line exercises, there were fraying on both ends. This usually happens when you are in a hurry, remember to place the pen carefully at the beginning of each line so it does not happen. There are wobbles in line and bowing happens especially in the longer lines; this tends to happen because of rushing, not ghosting and not using shoulder enough, take your time, no need to rush this course.

On planes, there are instances where your ellipses wobble, its better to prioritize confidence over accuracy.

On the ellipses section, your elipses improved here. Even tho some are overlapping your confidence has improved.

On rotated boxes, i recommend you adding lineweight to the front edges so it is easier to read. The rotation of the box is good however you have to keep working on lines.

Organic perspective is fine but then you repeated lines which you shouldnt, you should keep the line as it if were correct and move on
