Hi Glint~

Okay, so, starting off, the superimposed lines look good. There's some minor corrections to their trajectory every so often, so, once your pen touches the page, try to keep your brain from interfering. The ghosted lines start off a little wobbly, but improve considerably by the time you reach the ghosted planes exercise. Still, remember that confidence is the #1 priority. Also, for the ghosted planes exercise, be sure to plot start/end points for your non-diagonal center lines, too. All lines need those.

The ellipses look good, though a lot of them tend to start off a little insecure, and then stabilize during the second rotation. Ellipses are notoriously annoying, so it's definitely a little scary to commit to them, but a confident ellipse that's lacking in accuracy is still good. A wobbly ellipse that isn't, isn't.

The box section is quite solid. For the rough perspective exercise, remember that lines that don't head to the VP can be parallel to the horizon, or perpendicular to it- nothing else. If your start/end points suggest a line that behaves differently, that line is incorrect, so don't commit to it. Also, be careful not to correct incorrect lines- it's a bad habit. Nice job on the rotated boxes exercise- it's quite clean! The organic perspective boxes, too, look nice, though some of the boxes are diverging, rather than converging. There's just the thing to fix this, though...
