Lines

In the ghosted lines you overshoot multiple times and this is also seen in the ghosted planes exercies, try lifting your pen when you reach your endpoint. There's also some wobbliness in your lines particularly in the ghosted planes exercise, and this is shown particularly in the organic, I'm guessing that since you focus on accuracy you lost confidence. Focus on confidence first I rather have strong solid lines that overshoot in rough perspective than shaky lines in organic perspective

Ellipses

Your ellipses are very good, they're confident and smooth, ngl kinda jealous

Boxes

Most of the issues are described in lines. In rotated boxes you drew one too many boxes on the horizontal and vertical axis so it kinda looks stretched out(without it the rotated boxes exercise is good)

Overall

Good work, just remember to focus on confidence even if it means overshooting your lines
