Hi! I’ll do things a bit differently, this time. This is a fantastic submission, so rather than go through the sections in order, I’ll just give you some quick pointers.

Be careful not to alter the trajectory of your lines, like in some of the longer superimposed lines. If a line runs off-course, boldly continue onto that course- don’t course-correct.

If you’re not already, use start/end points for the non-diagonal center lines of your planes. If the line stops short of them, do not extend it. It’s far wiser to leave your mistakes be, usually.

Remember that, despite the complexity of some of the latter exercises, the technical aspects remain unchanged- all you’re doing is drawing a line from point A to point B. If it can be confident in the ghosted lines exercise, it can be confident elsewhere, too. (re: wobble in rough perspective.)

Other than that (and even that was just nitpicks, but I had to say something! xD), this is a really solid submission. Onto the next~
