Hello Fan, I will be reviewing your submission today,

Superimposed Lines: mostly solid but arching can be noticed. It'll diminish with practice or you can arc in the opposite direction, but just keep it in mind. I'd also suggest that you try more complex curves, like S curves and swirls for example.

Ghosted lines: as mentioned previously, a slight arc can be perceived. Remember to prioritize smoothness over accuracy. It is also worth mentioning that you should not be trying to correct lines, no matter how off they turn out.

Ghosted planes: Again, don't go over your original lines in an attempt to correct them.

Table of Ellipses: Remember they should fit snuggly, without overlapping.

Plotted Perspective: Your hatching seems to be scribbled. Remember that you should start at one side of the box's face and perform a smooth stroke to the other side.

Rough Perspective: This is were your line quality suffered the most. There are lots of instances were you attempted to correct lines and even chicken scratched. Once again remember to ghost your lines and perform a confident stroke that prioritizes smoothness over accuracy. You also seem to have attempted a more complex perspective at the end of it, however I'd advise against this. Just because an exercise is harder doesn't mean you're getting any more out of it, if anything you may just be diluting the intended learning concepts. Just stick to what you are being asked to do. In this case, you misunderstood the point of the exercise. You were not supposed to extend your lines to the VP, but to the horizon line instead, so that you could see where the lines you were drawing were actually headed. Compare yours to this and take a look at how the lines were extended.

Rotated Boxes: Lacks use of line weight or hatching to create visual hierarchy.

Organic Perspective: a lot of my previous comments on line quality still apply here and you left a box open ended. You should also keep in mind that your boxes should be growing at a consistent rate as they approach the viewer.

Conclusion: You started with good confident line quality, but as the exercise shifted focus your line quality suffered heavily. Keep in mind the points listed above an redo the rough perspective exercise.

Best of luck moving forward
